Weegy: Ralph spends 15 1/3 hours per month playing tennis. In a year he plays tennis for 184 hours. 15 1/3 = 46/3 *12 = 184 hrs.
User: What's the difference between 126 1/4 and 78 2/3?
Weegy: 126 1/4 - 78 2/3 = 505/4 - 236/3 = ((505 * 3) - (236 * 4)) / (4 * 3) = (1515 - 944) / 12 = 571/12 = 47 7/12.
