Answer: 27 girls are wearing blue shorts.
18 boys are wearing blue shorts.
Step-by-step explanation:
5/7 of the 63 students in gym class are wearing blue shorts. This means that the total number of students in the class wearing blue shorts is
5/7 × 63 = 45 students
The ratio of the number of girls wearing blue shorts to the total number of students wearing blue shorts is 3:5
If the number of girls wearing blue shorts is x, then
x/45 = 3/5
Cross multiplying, it becomes
x × 5 = 45 × 3
5x = 135
x = 27
The number of boys wearing blue shorts would be
45 - 27 = 18
