The ratio boy to girl in me. baker social studie class is 2 to 3 if there are 30 total students in class how many girls are in the class than boy

well we can set up this proportion.

2 boys

3 girls

Now lets add this together to equal a smaller proportion class.

2 boys + 3 girls = 5 students.

We need for their to be 30 students.

So what number can we multiply them by to get 30 students in all when added.

Well we can divide 30 ÷ 5 = 6

so multiply each number.

2 boys x 6 = 12

3 girls x 6 = 18

these two numbers add up to 30 and when this fraction is simplified it is 2/3

So your finally answer is

12 boys and 18 girls.

Good Luck! :)
