The answer is A.

Step-by-step explanation:

First, you have to make mixed number into an improper fraction:

5 2/5 = (5*5) + 2 / 5

= 27/5

4 1/8 = (4*8) + 1 / 8

= 32+1 / 8

= 33/8

Next is to divide the fractions by multiplying an upside down fractions:

27/5 : 33/8

= 27/5 * 8/33

= 9/5 * 8/11

= (9*8) / (5*11)

= 72/55

= 1 17/55

A) 117/55
