The ratio of boys to girls is 7:5. If there are 42 boys, how many girls are there?

Explanation:
In a ratio, each part is the same size. A 7:5 ratio means 7 parts for boys and 5 parts for girls. If there are 42 boys, those 7 parts total 42, so one part equals 42 ÷ 7 = 6. The girls are 5 parts, so 5 × 6 = 30. There are 30 girls.
