Subtracting Fractions with the Same Denominator
Grade 4 · Math · Fractions and Decimals · Ontario, 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.
