Question

sam makes 300 cupcakes all of the cupcakes are lemon, chocolate and vanilla flavour. 1/10 of the cupcakes are lemon. 1/4 of the cupcakes are chocolate . work out how many of the cupcakes are vanilla

Answer 1

Explanation:

1/4 of 300 is equal to 75

1/10 of 300 is equal to 30

75 + 30 = 105

300 - 105 = 195

195 cupcakes are vanilla.

195/300 = 65% of the cupcakes are vanilla

13/20 of the cupcakes are vanilla/195 cupcakes are vanilla.
