SUBTRACT THE NUMERATORS

With matching denominators, take away the top numbers and keep the bottom one. 4/7 - 2/7 = 2/7. The pieces stay the same size, you simply have fewer of them.

4/5 − 2/5

1Same denominator? Yes! (5)

2Subtract numerators: 4 − 2 = 2

3Keep denominator: 2/5

LEADER TIP

Mirror the addition approach: denominator stays, numerators subtract. Concrete before abstract.
