15 1/3 per month. Since their is 12 months in a year, we can multiply 15 1/3 by 12 to get our answer.

To multily, we need to transform 15 1/3 into a improper fraction.

15*3 + 1 = 45+1 = 46

46/3 * 12/1

46*12 = 552

3*1=3

552/3 is the improper fraction, we must make it mixed so that we can have a more simple answer.

552/3 = 184

Therefore, the whole number is 184

Our final answer: In one year, Ralph spends 184 hours.
