Question

The ratio of students
who were enrolled in
gym class to the
number of students
who were not enrolled
in gym class was 10:3. If
there were 346
students, how many
were enrolled in gym
class?

Answer 1

10x + 3x = 13x students
But 13 does not divide 346
260+78 = 338
270+81 = 351
I suspect a typo
