Question

jack and jill shared 1/2 of a cake. jack got to eat twice the amount of cake as jill. what fraction of the cake did jack eat.

Please Help :I

Answer 1

Jack's share of the total cake is 1/3

Total fraction of cake = 1/2

Let :

Jill's share = x

Jack's share = 2x

Jack's share + Jill's share = total fraction of cake

x + 2x = 1/2

3x = 1/2

x = (1/2 ÷ 3)

x = (1/2 × 1/3) = 1/6

Jack's share = 2x = 2(1/6) = 2/6 = 1/3

Hence, Jack's share of the cake is 1/3
