In Mrs. Wilson's math class, the ratio of girls to total students is 5 to 8. If there are 24 total students, how many boys are in the class? (help please! i also need work for understanding this problem, thank you!)
I changed 5:8 to have a denominator of 24. So I multiplied the 5 and 8 by 3. This makes 15 for the numerator. 15 is the amount of girls. The total number of students is 24, so 24-15 is 9.
