Question

A class had 6 students absent one Monday. This was 2/7 of the entire class. How many students were present that day?

Answer 1

21 students

Explanation:

Let c = number of students in class

c* 2/7 = 6

Multiply each side by 7/2

c * 2/7 *7/2 = 6 *7/2

c = 21

There are 21 students in the class
