At Mariah's birthday party, 9 of her friends ate 3/4 of her chocolate cake. How much cake did each friend eat?

Answer 1

To find out how much cake each friend ate, we can divide the amount eaten by the number of friends.

9 friends ate 3/4 of the cake.

To divide the cake equally, we can divide 3/4 by 9:

(3/4) ÷ 9 = (3 ÷ 4) ÷ 9 = 3 ÷ (4 x 9) = 3 ÷ 36 = 1/12

Each friend ate 1/12 of the chocolate cake.
