Question

For every 7 glasses wearers in a Classroom,there are about 13 non glasses wearers.If there are 32 students in a entire class how many students are non glasses wearers

Answer 1

The answer is 11, How I got my answer.

First I added 7+13=20, so now I can find the percentage, which is 35% of 20=7, so then I found that 35% of 32=11.2, so now I just round it off.

I hope this helps!
