Fractions of quantities

To find a fraction of a quantity:

  • Divide the quantity by the denominator

  • Multiply the answer you get by the numerator

To find 2/ 5 of £15, for example:

  • Divide 15 by 5 (the denominator): 15 ÷ 5 = 3

  • Multiply the answer 3 by 2 (the numerator): 3 x 2 = 6

  • So 2/ 5 of £15 is £6
