Question

There are 34 black marbles, 17 red marbles, 53 blue marbles, and 13 white marbles in a box. What fraction of all the marbles are not black?

Answer 1

83/117

Explanation:

For the denominator, it would be the total of marbles. So I added all the numbers and got 117.

For the numerator, it would be how many marbles are not black. So how many total marbles minus the black marbles. So 117 minus 34.
