Question

Maria has baked a cake for Cathy's birthday. The dimensions of the cake are inches by inches. The cake is going to be cut into squares with each piece being approximately 5.55% of the cake, which should give a total of

pieces of cake with each piece having a side length of
inches.

Answer 1

The cake will be cut into 18 square pieces and each piece would have a side length of 2 1/4 inches.

Explanation:

Since the cake is going to be cut into squares with each piece being approximately 5.55% of the cake, to find the number of pieces of cake divide 100% by 5.55%.

Therefore, the cake will be cut into 18 square pieces.

The dimensions of the cake are 13 1/2 inches by 6 3/4 inches and it is going to be cut into 18 square pieces. Since the length is twice the width, there should be twice as many cuts along the length than there are along the width. Thinking of the factor pairs of 18, only 6 and 3 have one factor that is twice the other. Divide the length by 6 and the width by 3. In both cases the division gives a length of inches. Therefore, the side length of each square piece of cake is 2 1/4 inches.

Answer 2

5.55% = 1/18

so, cut the cake into 18 equal squares.

The cake is twice as long as it is wide, so that means cut half the cake (6 3/4 x 6 3/4) into 9 pieces, each with a side of 1/3 * 6 3/4 = 2 1/4 inches.
