girls = ???
boys = ???

(Please leave a step-by-step explanation)

Answer 1

Girls = 700

Boys = 1,750

Explanation:

A ratio of 2 to 5 means that for every 2 girls present, there are 5 boys present. Therefore, for every 7 students present, 2 are girls and 5 are boys. In other words, 2/7 of the students are girls and 5/7 are boys. To find the total number of girls and boys present, we can multiply the total number of students by the fractions given above.

Girls = 2,450 * (2/7)

Girls = 700

Boys = 2,450 * (5/7)

Boys = 1,750
