Im pretty sure there is 145 students
252, 210 divided by 5 = 42, 42 x 5 = 210 + 42= 252
1. We know that 30% expressed as a decimal is 0.30
Since 30% of people were using the internet, 0.30*3200 is our answer.
3200*0.30= 960.
Therefore 960 people were using the internet out of the 3200 surveyed.
I hope this helps you
