Equivalent fractions · Year 5

In Year 5 you learn: simplifying fractions.

Equivalent fractions look different but stand for the same amount: 1/2, 2/4 and 5/10 all cover half of a shape. Spotting them lets you simplify answers, compare fractions and, later, add them.

Key facts

  • Multiply or divide the top AND the bottom by the same number to make an equivalent fraction.
  • Adding the same number to the top and bottom does NOT keep a fraction the same: 1/2 is not equal to 2/3.
