Question

If m and n are positive two-digit numbers, then, of the following fractions, the one with the largest value is:

Answer 1

B.
 I used the number "10" as an example.
10+1/10-1= 11/9 which out of the current options, seems to give the largest value.

Answer 2

Just like the person said in the comments, the answer is b, because it gives a greater numerator to the lower denominator.
