How to Subtract Mixed Numbers

Introduction

The key to subtracting mixed numbers is converting them into improper fractions. Once they are improper fractions they are easier to subtract because you can turn the denominators so that they are common. Therefore, subtraction of mixed numbers is a piece of cake!

Subtracting Mixed Numbers: Example

Let's say that you have 4 2/4-2 3/4. The first step is to turn the mixed numbers into improper fractions:
4 2/4=18/4
2 3/4=11/4
Next, you simply subtract the numerators. Remember that the denominators stay the same: 7/4.
The final step is that you have to convert the improper fraction into a mixed number: 1 3/4.
Therefore the difference of 4 2/4-2 3/4=1 3/4.
Now wasn't that easy!
