Question

Betty is baking cakes to sell slices in her bakery. Each cake has 8 slices. She carefully adds an icing design, using 1/3 cup of icing for each slice. If she plans to bake 4 1/2 cakes, how many cups of icing will she use?

Answer 1

Answer: 12 cups

Explanation:

Number of slices in a cake = 8 slices

Number of cups of icing used by each slice = 1/3

Number of cups of icing for each cake will then be:

= 1/3 × 8

= 8/3

= 2 2/3 cups of icing

If she plans to bake 4 1/2 cakes, the number of cups of icing will she use will be:

= 4 1/2 × 2 2/3

= 9/2 × 8/3

= 72/6

= 12 cups of icing
