Quantitative Literacy Practice Exam 2025 – Comprehensive Preparation Guide

To find the adult-to-child ratio from the given information, we first need to determine the number of adults among the 84 people. Since there are 32 children, we can calculate the number of adults by subtracting the number of children from the total number of people:

84 (total people) - 32 (children) = 52 adults.

Next, we can set up the ratio of adults to children. The ratio is formulated as the number of adults to the number of children, which gives:

52 adults : 32 children.

To simplify this ratio, we can divide both numbers by their greatest common divisor. In this instance, both numbers can be divided by 4:

52 ÷ 4 = 13

32 ÷ 4 = 8

Thus, the simplified adult-to-child ratio is 13:8. However, the question asks specifically for the ratio in the adult-to-child format, which can be interpreted as 8:13.

This is why the correct answer aligns with the calculations and leads to the conclusion that the adult-to-child ratio is indeed 8:13, confirming that the ratio format is appropriate for the context provided.
