Question

A bag contains red and blue counters in the ratio 3:8

there are 24 blue counters in the bag
how many red counters are there?

Answer 1

Since the ratio is 3:8, you would have to find the multiples of 8 and 3
8 x 3 = 24
3 x 3 = 9
So your answer is 9 red counters

Answer 2

you would take 24 divided by 8 and then multiply it by 3
