Answer 1

87 students

Explanation:

We know

12 out of every 15 students owns a cell phone, so the ratio of student who owns cell phone is 12:3. For every 15 students, there are 12 own cellphones, and 3 do not.

To find there are 435 students surveyed, how many do not own a cell phone? We take

435 / 15 = 29

3 x 29 = 87 students

So, 87 students do not own a cellphone.
