If the ratio of boys to girls is 3 to 2 and there are 25 students, how many are boys?

You're testing how to apply a ratio to a total. A ratio of three to two divides the group into five equal parts, three parts for boys and two for girls. With twenty-five students, each part has five students. The boys' share is three parts, so three times five equals fifteen. Therefore there are fifteen boys.
