Improper Fractions to Mixed Numbers

Converting an improper fraction to a mixed number is a very useful skill to learn that helps students to understand fractions and how to express them in different ways. It also teached them about fractions of a whole, and more advanced things like the greatest common factor (GCF) when simplifying fractions.

In this article, we'll explain how to convert any improper fraction into a mixed number with links to a lot of different examples to help you fully understand the concept.

The first step is to make sure we understand all of the terms in the problem we are trying to solve. We'll use the example of 64:

  • Numerator - this is the number above the fraction line. For 64, the numerator is 6.
  • Denominator - this is the number below the fraction line. For 64, the denominator is 4.
  • Improper fraction - an improper fraction is when the numerator is greater than the denominator.
  • Mixed number - A mixed number is a way to express the improper fraction by converting it to a whole number (an integer) and a smaller proper fraction.

Find the Whole Number of Improper Fraction 64

To convert this to a mixed number, we need to find out what the whole number of our new fraction should be. To do that we divide the numerator by the denominator and round the answer down so that we have a whole number with no decimal places:

6 ÷ 4 = 1.5

As you can see, 1.5 is not a whole number, and so we have to round this down to 1.

Get the New Numerator

We have the whole number, so we now need to calculate the new proper fraction, starting with the new numerator.

In this step, we take the whole number we just calculated, 1, and multiply it by the denominator, which is 4. The result of that calculation is then subtracted from the original number, 6:

6 - (1 × 4) = 2

Complete the Mixed Fraction

The good news is that the denominator in a mixed number is the same as the original improper fraction. All we need to do is take the new numerator and put it above the original denominator, with the whole number before it:

1 2 4

Simplifying 24 to Lowest Terms

You might have noticed that the new fraction part of the mixed number, 24, can be simplified down to lower terms.

To do this, we need to calculate something called the greatest common factor (GCF) of those two numbers. Sometimes this is called the greatest common divisor (GCD). This is the smallest number that both 2 and 4 can be divided by.

The GCF of 2 and 4 is 2. We can now divide both by the GCF to find the simplified fraction:

2 ÷ 2 = 1

4 ÷ 2 = 2

This gives us a final answer with a simplified proper fraction of 12:

1 1 2
