Answer:

D. 184

Step-by-step explanation:

There are 12 months in one year.

If he spends 15 1/3 hours per month playing tennis, then he spends 12 * 15 1/3 hours per year.

We need to multiply 12 by 15 1/3.

12 * 15 1/3 =

= 12(15 + 1/3)

= 12 * 15 + 12 * 1/3

= 180 + 4

= 184

He spends 184 hours per year playing tennis.
