Ralph spends 15 1/3 hours per month playing tennis. how many hours does he play tennis in a year.

If Ralph plays 15 hours and 20 minutes of playing tennis per month all we need to do is multiply by 12.
15 1/3*12/1
We need 15 1/3 an improper fraction soo 15*3+1 is 46.
46/3*12/1
552/3 Now to simplify.
3 go into 552, 184 times.
So 184 hours he plays tennis a year.

15 1/3 + 12/1 = 46/3 + 12/1 = ((46 × 1) + (12 × 3)) / (3 × 1) = (46 + 36) / 3 = 82/3 = 27 1/3 do you understand?
