Question

A bag of marbles comes with 3 blue marbles, 2 red marbles, and 5 yellow marbles.

What is the ratio of RED MARBLES to ALL THE MARBLES?

2 to 5

2 to 10

2 to 8

2 to 3

Answer 1

B

Explanation:

There are 2 red marbles so the ratio will start with 2, there are also 3 (blue marbles) + 5 (yellow marbles) = 8 marbles. But it says ALL the marbles so also add the red ones, 8 + 2 = 10. The answer is 2 to 10.

Answer 2

There are 2 red marbles
There are 10 marbles in total

2 red marbles to 10 in total
2 to 10

Answer: 2 to 10
