50% 0f all the cakes jenny baked that week were party cake,1/5were fruit cakes and the reminder were sponge cakes .what percentage of cakes were sponge cake?

first you must convert 1/5 to a % 1/5 = 20% fruit cakes 50% party cakes 100%- 70%= 30% left for sponge cakes hope this helps

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
