In the 6th grade classes there are 4 girls for every 3 boys if there are 24 girls how many boys are there?

Step-by-step explanation: The correct answer is 18 boys.

First of all, we know that there is a ratio of 4 girls to three boys or 4:3.

Next we know that there are 24 girls so what we have to do is figure out which number 4 was multiplied by to get 24.

4 times 6 is 24 so since we know that four was multiplied by 6, we can now multiply 3 by 6 to keep the same ratio of girls to boys.
