Subtracting Fractions with the Same Denominator

Grade 4 · Math · Fractions and Decimals · Newfoundland and Labrador, Canada

Lesson Summary

When two fractions have the same bottom number, subtract the top numbers and keep the bottom the same.

Explanation

Subtracting fractions with like denominators works the same way as adding, except you subtract the numerators. For 7/9 − 2/9, subtract the top numbers: 7 − 2 = 5, so the answer is 5/9. The denominator stays the same because the size of each piece has not changed. Always check if you can simplify the answer. For instance, 4/8 simplifies to 1/2.
