Question

The ratio of boys to girls is 3:4 if there are 48 girls, what is the total number of sixth graders

Answer 1

84

Explanation:

The 4 part of the ratio relates to 48 girls, then

48 ÷ 4 = 12 ← value of 1 part of the ratio , then

3 parts = 3 × 12 = 36 ← number of boys

total number of students = 48 + 36 = 84
