Converting Mixed Numbers to Improper Fractions

Mixed numbers and improper fractions are two types of fractions that you come across while learning arithmetic. A mixed number is a combination of a whole number and a proper fraction, whereas an improper fraction is a fraction where the numerator is greater than or equal to the denominator. Sometimes in math, you might be required to change a mixed number to an improper fraction to simplify calculations. In this article, we will explore the process of converting mixed numbers to improper fractions in a relaxed and straightforward language.

To begin with, let’s define what we mean by a mixed number. A mixed number is a combination of a whole number and a fraction. For example, 1 1/4 is a mixed number, where 1 is a whole number, and 1/4 is a proper fraction. On the other hand, an improper fraction is a fraction where the numerator is greater than or equal to the denominator. For instance, 5/4 is an improper fraction because the numerator (5) is greater than the denominator (4). Now that we understand what mixed numbers and improper fractions are let’s learn how to convert mixed numbers to improper fractions.

The Basics: What is a Mixed Number and an Improper Fraction?

Before we dive into the process of converting a mixed number into an improper fraction, let’s first understand the difference between a mixed number and an improper fraction.

A mixed number is a combination of a whole number and a proper fraction. For instance, 2 ⅔ is a mixed number as it comprises a whole number 2 and a proper fraction ⅔.

In contrast, an improper fraction represents a fraction with a numerator greater than or equal to the denominator. For example, 7/3 is an improper fraction as its numerator 7 is greater than the denominator 3.

Why Convert Mixed Number into Improper Fraction?

Before we learn the procedure to convert mixed numbers into improper fractions, let’s understand why it is necessary. In some cases, it may be beneficial to convert mixed numbers into fractions, especially in the context of mathematical operations such as multiplication, division, and addition.

In general, improper fractions are easier to work with compared to mixed numbers. Therefore, converting mixed numbers into improper fractions can simplify complex calculations.

The Procedure to Convert Mixed Number into an Improper Fraction

The procedure to convert a mixed number to an improper fraction can be broken down into following steps:

Step 1: Multiply the Whole Number and the Denominator

The first step is to multiply the whole number and the denominator of the fraction. This will give us the numerator for the improper fraction.

For example, let’s take the mixed number 2 ⅔. To convert it into an improper fraction, we multiply the whole number 2 with the denominator of the proper fraction 3, resulting in 6.

Step 2: Add the Numerator to the Result of Step 1

The second step is to add the numerator of the fraction to the result of step 1.

In our example, we add the numerator of ⅔ to the result of step 1 which is 6. This gives us the numerator of the improper fraction, which is 8.

Step 3: Write the Result as an Improper Fraction

Finally, write the result of step 2 as a fraction with the numerator obtained in step 2 and the denominator of the original proper fraction. This gives us 8/3 as the improper fraction equivalent of the mixed number 2 ⅔.

Examples of Converting Mixed Numbers into Improper Fractions

Let’s take some more examples to illustrate how to convert mixed numbers into improper fractions:

Example 1:

Convert 3 ¼ into an improper fraction.

Step 1: Multiply the whole number 3 with the denominator 4. This gives us 12.
Step 2: Add the numerator 1 to the result of step 1, which is 12. This gives us 13 as the numerator of the improper fraction.
Step 3: Write the result as an improper fraction with the numerator 13 and the denominator 4. Thus, 3 ¼ can be represented as 13/4 in the form of an improper fraction.

Example 2:

Convert 5 ⅘ into an improper fraction.

Step 1: Multiply the whole number 5 with the denominator 5. This gives us 40.
Step 2: Add the numerator 4 to the result of step 1, which is 40. This gives us 44 as the numerator of the improper fraction.
Step 3: Write the result as an improper fraction with the numerator 44 and the denominator 5. Thus, 5 ⅘ can be represented as 44/5 in the form of an improper fraction.

The Bottom Line

Steps to convert mixed numbers into improper fractions

Converting mixed numbers to improper fractions can be a little tricky, but once you know the steps, it becomes a lot easier. Here are the steps to follow:

Step 1: Rewrite the mixed number as a fraction

The first step in converting a mixed number to an improper fraction is to rewrite it as a fraction. To do this, you need to multiply the whole number by the denominator of the fraction and then add the numerator. For example, if the mixed number is 2 1/3, you would multiply 2 by 3 and add 1 to get 7. The fraction would then be 7/3.

Step 2: Simplify the fraction if possible

After you’ve rewritten the mixed number as a fraction, the next step is to simplify the fraction if possible. You can do this by finding the greatest common factor (GCF) of the numerator and denominator and dividing both by it. For example, if the fraction is 7/3, you can simplify it by finding the GCF of 7 and 3, which is 1. Then, you divide both the numerator and denominator by 1, resulting in 7/3.

Step 3: Write the improper fraction

Once you have simplified the fraction, the next step is to write it as an improper fraction. To do this, you simply write the numerator over the denominator. For example, if the fraction is 7/3, the improper fraction would be 7/3.

Step 4: Add whole number to final answer

The final step is to add the whole number back to the improper fraction to get the mixed fraction. To do this, you need to divide the numerator by the denominator. The quotient is the whole number and the remainder is the numerator. For example, if the improper fraction is 7/3, you would divide 7 by 3, which is 2 with a remainder of 1. The mixed fraction would then be 2 1/3.

Step 5: Practice, Practice, Practice!

The more you practice converting mixed numbers to improper fractions, the easier it will become. Try working through several problems on your own using the steps outlined above. You can also find plenty of worksheets and online tutorials to help you improve your skills.

In conclusion, converting mixed numbers to improper fractions may seem daunting at first, but it’s a simple process that you can master with a little practice.
