Section 3: Subtracting Fractions

Illustration of mathematical shapes and symbols in different colors

When both denominators are the same, subtract the numerators (the top numbers) and write the result on the top of a line; then write the denominator under that line.

5 over 8 - 2 over 8 = ?

Check to see if the denominators are the same. They are both 8.

Subtract the numerators:

5 - 2 = 3

Write the result on the top of a line and the denominator under that line:

3 over 8

Let's try another one:

7 over 9 - 1 over 9 = ?

Check to see if the denominators are the same. They are both 9.

Subtract the numerators:

7 - 1 = 6

Write the result on the top of a line and the denominator under that line:

6 over 9

Try the next one on your own:

3 over 4 - 2 over 4 = ?

Check to see if the denominators are the same.

Subtract the numerators.

Write the result on the top of a line and the denominator under that line.

Try one more:

12 over 25 - 10 over 25 = ?

Check to see if the denominators are the same.

Subtract the numerators.

Write the result on the top of a line and the denominator under that line.

Your teacher will give you more fractions to subtract. If you need help, your teacher will show you more about subtracting fractions.
