Question

Maria bought a cake and divided it equally among her 4 children. Ana and Benito ate their whole piece, Carlos ate half of his piece and Diana only ate a fifth of hers. What slice of the cake was left over?

Answer 1

the answer isnt on there but i got 27/40.....

Explanation:

1 cake + 4 kids = 4 pieces of cake

Ana ( one full piece) + Benito ( one full piece) = 2/4 or 1/2

so we already know half the cake is gone.

Carlos ate half, so 1/2 of 1/4 equals 1/8

Diana ate 1/5 of her's, so 1/5 of 1/4 equals 1/20

now, we add.

1/4 + 1/4 + 1/8 + 1/20 = 27/40

Answer 2

70/200

Explanation:

1/8+1/20

5/40+2/40

70/200
