Decimal PSLE 2010 P2 Q3

Meijun had some money. She used 1/4 of it on a watch and 1/6 of it on a gift. The watch and the gift cost $133.50 altogether.How much money had she left?


1/4 x 3/3 = 3/12

1/6 x 2/2 = 2/12

3 + 2 = 5

12 - 5 = 7

5 u  -->  133.50

7 u  -->  7/5 x 133.50 =  $186.90


She had $186.90 left.
