Converting decimal fractions to fractions
Converting a decimal fraction to a fraction involves determining the place value of each digit to the right of the decimal point. Each digit represents a power of 10, with the first digit to the right of the decimal point representing tenths, the second digit representing hundredths, and so on.
To convert .88 to a fraction, we can write it as 88/100. However, this fraction can be simplified further.
To simplify a fraction, we need to find the greatest common divisor (GCD) of the numerator and denominator. The GCD is the largest number that divides evenly into both numbers.
Finding the greatest common divisor
To find the GCD of 88 and 100, we can list the factors of each number and find the largest one they have in common.
The factors of 88 are: 1, 2, 4, 8, 11, 22, 44, and 88.
The factors of 100 are: 1, 2, 4, 5, 10, 20, 25, 50, and 100.
The largest number that appears in both lists is 4. Therefore, the GCD of 88 and 100 is 4.
Reducing the fraction to its simplest form
To reduce the fraction 88/100 to its simplest form, we divide both the numerator and denominator by their GCD, which is 4.
Dividing 88 by 4 gives us 22, and dividing 100 by 4 gives us 25. Therefore, the simplified form of 88/100 is 22/25.

Simplifying .88 as a Fraction
When we have a decimal number like .88, we can convert it into a fraction to express it in a different form. In this section, we will explore how to simplify .88 as a fraction, making it easier to work with and understand.
Finding the greatest common divisor
To simplify .88 as a fraction, we need to find the greatest common divisor (GCD) of the decimal number. The GCD is the largest number that divides evenly into both the numerator and the denominator of the fraction.
For .88, the numerator is 88 and the denominator is 100. To find the GCD, we can list the factors of both numbers and identify the largest common factor. In this case, the factors of 88 are 1, 2, 4, 8, 11, 22, 44, and 88. The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. The largest common factor is 4.
Reducing the fraction to its simplest form
After finding the greatest common divisor, we can simplify the fraction by dividing both the numerator and the denominator by the GCD. In this case, dividing 88 by 4 gives us 22, and dividing 100 by 4 gives us 25.
Therefore, .88 simplified as a fraction is 22/25. This means that if we divide a whole into 25 equal parts, .88 represents 22 of those parts.
Simplifying fractions not only makes them easier to work with mathematically, but it also provides a clearer representation of the original decimal value. In this case, .88 is equivalent to 22/25, which allows us to understand the decimal in terms of a fraction.
Converting .88 to a Mixed Number
Understanding mixed numbers
A mixed number is a combination of a whole number and a proper fraction. It represents a value that is larger than one, but not a whole number.
To understand mixed numbers, let’s consider an analogy. Imagine you have a pizza that is divided into eight equal slices. If you have eaten seven slices, you would have consumed 7/8 of the pizza. In terms of mixed numbers, this would be represented as 7/8. However, if you also had an additional whole pizza, you would have a total of 1 and 7/8 pizzas. This is an example of a mixed number, where the whole number part represents the number of complete pizzas, and the fraction represents the remaining slices.
Converting decimals to mixed numbers
Now, let’s focus on converting the decimal number .88 into a mixed number. To do this, we need to determine the whole number part and the fraction part of the decimal.
First, let’s consider the decimal .88. This can be interpreted as 88 hundredths. Since there are 100 hundredths in a whole, we can express .88 as a fraction by dividing 88 by 100:
.88 = 88/100
To simplify this fraction, we can find the greatest common divisor (GCD) of the numerator (88) and the denominator (100). The GCD helps us find the largest number that evenly divides both the numerator and the denominator.
Next, we reduce the fraction to its simplest form by dividing both the numerator and the denominator by their GCD:
88/100 = 22/25
Now that we have the fraction 22/25, we can convert it into a mixed number. To do this, we divide the numerator (22) by the denominator (25). The quotient becomes the whole number part, and the remainder becomes the fraction part:
22 ÷ 25 = 0 remainder 22
Therefore, the mixed number equivalent of .88 is 0 22/25.
By understanding mixed numbers and converting decimals to fractions, we can easily express decimal values like .88 in terms of mixed numbers, providing a clearer representation of the quantity.
Converting .88 to a Percent

They are commonly used in various real-life situations, such as calculating discounts, determining interest rates, or analyzing statistical data.
Now, let’s dive into converting decimals like .88 to percentages. Converting a decimal to a percent involves multiplying the decimal by 100. In this case, we want to convert .88 to a percent.
Understanding
Percentages are essentially a way to express a part of a whole as a fraction of 100. The word “percent” literally means “per hundred.” For example, if we say that 70% of a group of people prefer chocolate ice cream, we mean that 70 out of every 100 people in that group prefer chocolate ice cream.
Percentages are used in many different areas of life, from calculating sales discounts and determining tax rates to analyzing data and measuring probabilities. They allow us to easily compare different quantities and understand their relative proportions.
Converting decimals to percentages
To convert a decimal like .88 to a percent, we multiply it by 100. In this case, .88 multiplied by 100 equals 88. So, .88 as a percent is 88%.

Whether you’re working with financial data, analyzing statistics, or simply trying to figure out a discount during a sale, understanding how to convert decimals to percentages is a valuable skill.
Adding .88 to a Fraction
When it comes to adding fractions, things can get a bit tricky, especially when they have different denominators. But fear not, because with a little bit of understanding and the right approach, you’ll be able to tackle this challenge with ease.
Adding fractions with different denominators
To add fractions with different denominators, the first step is to find the least common denominator (LCD). The LCD is the smallest multiple that both denominators can divide into evenly. Once you have the LCD, you can proceed to add the fractions together.
Finding the least common denominator
Finding the LCD involves identifying the common factors between the denominators and then selecting the smallest one. Let’s take an example where we want to add the fraction 1/4 to the decimal 0.88. The fraction has a denominator of 4, while the decimal has no denominator. To make them compatible, we need to convert the decimal into a fraction.
To convert the decimal 0.88 into a fraction, we can consider it as 88/100. By simplifying this fraction, we get 22/25. Now we have two fractions with different denominators: 1/4 and 22/25.
To find the LCD, we need to determine the smallest number that both 4 and 25 can divide into evenly. In this case, the LCD is 100. Now that we have the LCD, we can proceed to add the fractions.
To add fractions with the same denominator, you simply add the numerators and keep the denominator the same. In our example, we have 1/4 + 22/25. By using the LCD, we can rewrite both fractions with the common denominator of 100:
1/4 becomes 25/100, and 22/25 becomes 88/100.
Now that both fractions have the same denominator, we can add the numerators:
25/100 + 88/100 = 113/100.
So, when we add 1/4 to the decimal 0.88, the result is 113/100.
Remember, adding fractions with different denominators may require finding the LCD and converting decimals into fractions. With practice, you’ll become more comfortable with these concepts and be able to tackle more complex fraction addition problems.
Subtracting .88 from a Fraction
When subtracting fractions with different denominators, it is important to find the least common denominator (LCD) first. The LCD is the smallest multiple that both denominators share, and it allows us to easily subtract the fractions.
Subtracting fractions with different denominators
To subtract fractions with different denominators, follow these steps:
- Find the least common denominator (LCD) of the fractions.
- Convert each fraction so that they have the same denominator as the LCD.
- Subtract the numerators of the fractions.
- Write the result as a fraction with the LCD as the denominator.
- Simplify the resulting fraction if necessary.
For example, let’s subtract 3/4 from 5/6:
- Find the LCD of 4 and 6, which is 12.
- Convert 3/4 to an equivalent fraction with a denominator of 12: (3/4) * (3/3) = 9/12.
- Convert 5/6 to an equivalent fraction with a denominator of 12: (5/6) * (2/2) = 10/12.
- Subtract the numerators: 10/12 – 9/12 = 1/12.
- The result, 1/12, is already in its simplest form, so no further simplification is needed.
Finding the least common denominator
To find the least common denominator (LCD) when subtracting fractions, follow these steps:
- Identify the denominators of the fractions.
- List the multiples of each denominator.
- Find the smallest common multiple of the denominators.
For example, let’s find the LCD for 4 and 6:
- The denominators are 4 and 6.
- The multiples of 4 are: 4, 8, 12, 16, 20, …
The multiples of 6 are: 6, 12, 18, 24, 30, … - The smallest common multiple of 4 and 6 is 12.
By finding the LCD, we can ensure that the fractions have the same denominator, making it easier to subtract them accurately.
Remember, when subtracting fractions with different denominators, always find the LCD first to simplify the calculation. This method ensures that the resulting fraction is in its simplest form and allows for a clear understanding of the subtraction process.
Multiplying .88 by a Fraction
When it comes to multiplying a decimal like .88 by a fraction, it’s important to have a clear understanding of how fractions and decimals work together. In this section, we will explore the process of multiplying .88 by a fraction and how to simplify the product.
Understanding multiplication of fractions
Before we dive into multiplying .88 by a fraction, let’s quickly review how multiplication of fractions works. When you multiply two fractions, you simply multiply the numerators (the top numbers) together and the denominators (the bottom numbers) together. The product is a new fraction that represents the result of the multiplication.
For example, if we have the fraction 2/3 and we multiply it by 4/5, we would multiply the numerators (2 and 4) to get 8, and multiply the denominators (3 and 5) to get 15. Therefore, the product of 2/3 multiplied by 4/5 is 8/15.
Simplifying the product
Now that we understand how to multiply fractions, let’s apply this knowledge to .88 multiplied by a fraction. To make things easier, we can convert .88 into a fraction. Since .88 is already a decimal fraction, we can express it as 88/100.
Next, let’s say we want to multiply .88 by the fraction 2/3. We can multiply the numerators (88 and 2) to get 176, and multiply the denominators (100 and 3) to get 300. Therefore, the product of .88 multiplied by 2/3 is 176/300.
To simplify this fraction, we can find the greatest common divisor (GCD) of the numerator and denominator, which is the largest number that divides evenly into both. In this case, the GCD of 176 and 300 is 4.
By dividing both the numerator and denominator by 4, we can simplify the fraction further. The simplified product of .88 multiplied by 2/3 is 44/75.
In summary, when multiplying .88 by a fraction, convert .88 into a fraction, multiply the numerators and denominators, and then simplify the resulting fraction by finding the GCD and dividing both the numerator and denominator by it.
Dividing .88 by a Fraction
When dividing .88 by a fraction, it’s important to understand the concept of division with fractions and how to simplify the quotient. This process allows us to find the result of dividing .88 by a fraction in its simplest form. Let’s explore the steps involved in this calculation.
Understanding division of fractions
Division of fractions involves dividing one fraction by another. In this case, we want to divide .88 by a fraction. To do this, we can follow a simple rule: “Dividing by a fraction is the same as multiplying by its reciprocal.”
To divide .88 by a fraction, we can rewrite .88 as a fraction by placing it over 1. So, .88 is equal to 0.88/1. Now, we can multiply 0.88/1 by the reciprocal of the fraction we want to divide by.
Simplifying the quotient
To simplify the quotient, we need to perform the multiplication and then simplify the resulting fraction, if possible.
Let’s consider an example to illustrate the process. Suppose we want to divide .88 by the fraction 1/2.
Step 1: Rewrite .88 as a fraction: .88/1.
Step 2: Multiply .88/1 by the reciprocal of 1/2. The reciprocal of 1/2 is 2/1.
Step 3: Multiply the numerators and denominators: (0.88/1) * (2/1) = (0.88 * 2)/(1 * 1) = 1.76/1.
The quotient of .88 divided by 1/2 is 1.76/1. However, we can simplify this fraction further by dividing both the numerator and denominator by their greatest common divisor (GCD).
To simplify the fraction 1.76/1, we find the GCD of 1.76 and 1, which is 1. Dividing both the numerator and denominator by 1 gives us the simplified quotient of 1.76.
So, dividing .88 by 1/2 results in a quotient of 1.76.
Remember, when dividing .88 by a fraction, always convert .88 to a fraction by placing it over 1. Then, multiply the fraction by the reciprocal of the divisor. Finally, simplify the resulting fraction, if possible, by dividing the numerator and denominator by their GCD.
