Question: There are 15 parents, 45 children and 3 teachers at a camp. What is the ratio of children to total people at the camp? a. 3:1 b. 5:2 c. 5:7 d. 1:3 e. None of the above
First, let's calculate the total number of people at the camp: 15 parents + 45 children + 3 teachers = **63 people** Now, the ratio of children to total people is: **Number of children : Total people = 45 : 63** Let's simplify this ratio by dividing both numbers by their greatest common divisor, which is 9: \( \frac{45}{9} = 5 \) \( \frac{63}{9} = 7 \) So, the simplified ratio is **5:7**. **Correct answer:** c. **5:7**
