Question

a club put its members into 5 groups for an activity. After 7 student have to leave early, there are only 3 students left to finish the activity. How many students were in each group.

Answer 1

2 students in each group

Explanation:

If there were 5 groups and after a while 7 students leave early and 3 students remain to do the activity, if you add 7 + 3 = 10 divide it by 5, the number of groups in the activity, you would get 2 students in each group.

Answer 2

There were 2 students in each group

Explanation:

Club members to start = C

7 students left early, and 3 remain

C - 7 = 3

Add 7 to both sides

C = 10

There were 10 students to start

Divided into 5 groups

10 ÷ 5

2

There were 2 students in each group
