Question

Suppose 52% of students chose to study French their junior year, and that meant that there were 312 such students. How many students chose not to take French their junior year?

Answer 1

288

Explanation:

If 52% studied French, then 48% didn't. The ratio of those who didn't to those who did is ...

(didn't study French)/312 = 48%/52% = 12/13

Then the number that didn't study French is ...

(didn't study French) = 312 × 12/13 = 288 . . . . . . multiply above by 312

288 students chose not to take French their Junior year.
