Question

The ratio of boys to girls in the checkers club at one school is 2:3. the number of club members is more than 20 and fewer than 30. how many club members are there?

Answer 1

So our ratio is 2:3, therefore we are looking for a multiple of 2 and a multiple of 3 that are proportional to this ratio. We can start by multiplying the ratio by 2, which gets us 4:6, which, since 4+6 is ten, is not a correct answer. If you continue the pattern of multiplying the ration with different numbers, you would eventually discover that, if you multiply the ratio by 5, you get 10:15. Since 10+15 is equal to 25, we know that this is the correct answer

Answer 2

I got the answer to be 10:15 is our ratio
