To solve this problem let's calculate each choice.
We have to check if the fraction on the right side equals the number we are trying to divide.
For example:
31 14/29 = 31 x 29 + 14 = 913 => Ok!
53 5/16 = 53 x 16 + 5 = 853 => Not ok!
4 8/25 = 4 x 25 + 8 = 108 => Not ok!
For last choice we get
53.25 x 16 = 852
However, the exercise tells us to find a fraction, so this choice is not okay either.
Answer: 31 14/29 = 31 x 29 + 14 = 913
