Question

A box contains 17 marbles, 13 blue marbles, and 23 white marbles. What is the part-whole ratio of red marbles in the box.

Answer 1

Since the ratio is part-Whole, first you need to find the whole. If you add all of the marble colors together (17+13+23) you get the total marbles (53) in the box. The ratio of red marbles to the total would be 17 to 53.
