Question

At a middle school, 18% of all seventh grades are teacher's aides. 64 seventh graders are teacher's aides, how many seventh graders are at the middle school? (Round to the nearest whole)

Answer 1

356 Seventh Graders

Explanation:

All I did was find out what number 64 was 18% of, and that gave me the answer. I took 64 and put it over 18%, and set it across from X over 100%. I did the cross multiplication, and got 355.56, but rounded it to get 356. So there are 356 total seventh graders. Hope this is helpful...have a great day! :))
