154 students

Step-by-step explanation:

First get the total number of students.

This can be gotten by

12% of A = 21

Where A represents the total number of students.

12% represents the % of A that chose to study French and 21 is the number of students that studied French.

Therefore,

12% / 100% x A = 21

0.12 x A = 21

Divide both sides by 0.12

0.12/0.12 x A = 21/0.12

A = 175

The total number of students is 175.

If 21 chose to study French their freshman year, number of students that chose not to will be total number of students minus number of those who chose to study French.

That's

175 - 21

= 154

154 students chose not to study French their freshman year
