    • How do you simplify multiplying fractions?

    We look for a number on the top and number on the bottom that can both be divided by the same number.

  • 5 and 10 are both in the 5 times table so can be divided by 5.
  • 5 ÷ 5 = 1 and 10 ÷ 5 = 2.
  • We can also see that 9 and 12 are both in the 3 times table and can be divided by 3.
  • 9 ÷ 3 = 3 and 12 ÷ 3 = 4.
  • 5/12 × 9/10 is the same as 1/4 × 3/2 .
