In a class with 25 students, if the ratio of boys to girls is 3:2, how many girls are there?

Explanation:
When a ratio is given, think in terms of parts. A 3:2 ratio means the class is divided into 5 equal parts: 3 parts for boys and 2 parts for girls. With 25 students in total, each part is 25 ÷ 5 = 5 students. Since girls occupy 2 parts, there are 2 × 5 = 10 girls. Quick check: boys would be 3 × 5 = 15, and 15 + 10 = 25, which matches the 3:2 ratio.
