In a marble collection, 1/8 of the marbles are blue. Of the blue marbles, 1/2 have sparkles. What fraction of the marbles in the collection are blue with sparkles?

Hello,

I believe the answer is 3/8 of the marbles in the collection are blue with sparkles.

I say so because if 1/8 of the marbles are blue and of the blue marbles, 1/2 of them have sparkles, the remaining of the marbles must be blue with sparkles.

Solution:

1/2 - 1/8 = 3/8

Thus, 3/8 of the marbles in the collection are blue with sparkles.
