Rewriting the fractions to have a common denominator:
8 7/12 = 8 + 7/12 = 8 + 73/123 = 8 + 21/36 = 8 21/362 5/8 = 2 + 5/8 = 2 + 59/89 = 2 + 45/72 = 2 45/72
Subtracting:
8 21/36 - 2 45/72 = 8 - 2 + 21/36 - 45/72 = 6 + 42/72 - 45/72 = 6 + (42 - 45)/72 = 6 - 3/72 = 6 - 1/24 = 5 23/24
Therefore, the result is 5 23/24.
