Advanced Number Properties: Remainder Questions

A question like this may seem very abstract at first. But you can simplify it by picking values for m and n that are easy to work with and that satisfy the limitations of the question.

To come up with good, simple numbers, add the remainder to the number you're dividing by: m divided by 7 leaves a remainder of 2, so pick m = 7 + 2 = 9; n divided by 7 leaves a remainder of 5, so n = 7 + 5 = 12.

Now it should be easy to solve the problem.
