In a class, the ratio of girls to boys is 3:4. If there are 9 girls in the class, how many boys are there?

Sagot :

Nine divided by three is three. Then, three times four equals 12. There are 12 boys in the class.
this is the equation 3:4=9:? sothats what  you want to find
so you have to multiply 9 and 4 is 36 after it your going to divide it with 3 so the answer is 12 so try to check it 

3:4=9:12 so to check your going to multiply 4 and 9 so =36 and 3 multiply 3 and 12 =36 if the two equation leads to the same answer thats the corect answer
