Question

me.Walker needs 22 cups of flour to bake 12 cakes.how many cups of. flour will she need to bake 30 cakes?

Answer 1

We can infer that more cups of flour are needed as the cakes are increased, so we can apply a rule of three, simple with direct proportion to find the answer:
12 cakes ----> 22 cups flour
30 cakes ----> x

x = (30)(22)/12
x = 55
therefore 55 cups of flour are needed to bake 30 cakes
