The ratio of boys to girls in a class is 3:2. If there are 35 students, how many are girls?
Hint
There are 5 total ratio parts.
Answer
14 girls.
Explanation
The ratio contains 5 parts. Each part represents 35 ÷ 5 = 7 students. Girls represent 2 parts, giving 14 girls.
Step-by-Step Solution
Total parts = 3 + 2 = 5
One part = 35 ÷ 5 = 7
Girls = 2 × 7 = 14
One part = 35 ÷ 5 = 7
Girls = 2 × 7 = 14
