What are equivalent fractions?
Equivalent fractions are different fractions that are the same size, like 1/2, 2/4 and 4/8. Multiply or divide the top and bottom by the same number and the fraction keeps its value: 2/3 = 8/12 because both parts were multiplied by 4.
To find the missing number, work out what the known bottom numbers were multiplied by, then do the same to the top. When that’s quick, try adding fractions.

Tips for equivalent fractions
Compare the two bottom numbers first: 3 → 12 is × 4, so the top is × 4 too.
To simplify, divide top and bottom by a number that goes into both.
Times tables help a lot here, so practise mixed times tables if the steps feel slow.
Equivalent Fractions questions and answers
How do you check two fractions are equivalent?
Cross-multiply: 2/3 and 8/12 are equivalent because 2 × 12 = 24 and 3 × 8 = 24.
