Subtract Fractions with Like Denominators

We can also subtract fractions with like denominators to find the difference between the fractions. As long as the denominators are the same, the fractions are alike, and we can simply subtract the numerators.

Here is an example done with pictures.

$\frac{6}{8} - \frac{3}{8} = \underline{\;\;\;\;\;\;\;\;\;}$

To solve this problem, we simply subtract the parts or the numerators. The difference between six and three is three. Then we put that answer over the common denominator.

Our final answer is $\frac{3}{8}$ .

We don’t need to simplify this fraction because three-eighths is already in simplest form
