50% of all the cakes Jenny baked that week were party cakes, 15  were fruit cakes, and the remainder were sponge cakes.  


What percentage of cakes were sponge cakes?     

Respuesta :

1/5= 20 percent. 50-20=30 percent sponge cakes.

Divide 5 into 1 and you will get .20. Turn it into 20 percent so you can subtract 50 from 20 and get 30%.
