Question

In Mr. Romero's auto shop class, the ratio

of boys to girls is 5:2. If there are 35 students
in the class, how many are boys?

Answer 1

boys 5:2 girls

add the ratio parts together

5 + 2 = 7

divide the total number of students by the total number of parts

35/7 = 5

now multiply each part of the ratio by 5

boys 25

girls 10

there are 25 boys
