Helen ate 1/10 of a cake. She divided The remainder into 3 equal portions. What fraction of the cake was in each portion
Vlad1618 [11]

Answer:

As she ate 1/10 of cake, we need to know how many cake remains after it, so we can substract:

1 - 1/10 = 10/10 - 1/10 = 9/10

Then, we need to divide the 9/10 into 3 portions:

(9/10) / 3 = 9/30 = 3/10

So we know the fractions would be 3/10 each on this situation..
