Simone Wu · Answer 1

In this case the best way to approach this is to turn one into a percentage, as this will make it easier. As you've got 1/5, turning this into a percentage will be 20%. Then simply add 50% and 20% together, giving you 70%, and subtracting this from 100%, giving you 30%. 30% of the cakes made were sponge cakes

Sidney Hickman · Answer 2

50% = 1/2 party cakes

1/5 = 20% fruit cakes

x=sponge cakes

50%+20%+x=100%

x = 100%-50%-20%

x=30%.
