kim used 3×3/5 cups of butter for baking a cake . the amount of sugar she used was 1/3 of the amount of butter used. how much sugar in cups did she use ?

Answer 1

Hard to tell if you mean 3 and 3/5 cups of butter or 3x3/5 = 9/5 cups of butter

Probably you mean 3 3/5 = 18/5 cups of butter

If sugar is 1/3 of the amount of butter, then 1/3 x 18/5 = 6/5 cups of sugar

If you really mean 3x3/5 or 9/5 cups of butter, then 1/3 x 9/5 = 3/5 cups of sugar
