Question

Russell randomly surveys seventh-graders in his school and finds that 6 of 30 attend summer camp. If there are 200 seventh-graders in his school, about how many are expected to attend summer camp?

Answer 1

40 seventh-graders are expected to attend summer camp.

6/30=x/200
6/30= 6 divided by 30= 0.2
0.2x200=40
