Question

Simon spent 1/3 of his pocket money on a computer game. He spent 1/4 of his pocket money on a ticket for a football match. Work out the fraction of his pocket money that he had left.

Answer 1

1/3 +1/4=4/12+3/12=7/12

Answer 2

3 x 4 = 12

12/12 - 1/3 ( so 4/12) = 8/12

8/12 - 1/4 ( so 2/12 as you only have 8/12 left) = 6/12

Answer =  6/12 = 1/2 or 50%
