72/160 = 9/20
72 over 480 in lowest terms is 3/20
20 over 72.[divide by 4]5 over 18[5 is prime, 18 is not divisible by 5; no further simplification possible]
The common denominator is 72, so 5/18 = 20/72, and 7/24 = 21/72. Now you can subtract the numerators [20-21 = -1]. So the answer is -1/72.
The answer is simple 1 over 8 or in other words 1/8.
