Question

1. the ratio of boys to girls in a math class is 3:2. if the class has 25 students in all, how many boys are in the class? a. 10 boys b. 15 boys c. 12 boys d. 13 boys

Explanation:

Step1: Determine total parts in ratio

The ratio of boys to girls is \(3:2\), so total parts \(= 3 + 2 = 5\).

Step2: Find value of one part

Total students are 25, so one part \(= \frac{25}{5} = 5\).

Step3: Calculate number of boys

Boys are 3 parts, so number of boys \(= 3\times5 = 15\).

Answer:

B. 15 boys
