To subtract these fractions, you need to find a common denominator. The least common multiple of 16 and 20 is 80. Converting 5/16 and 3/20 to have a denominator of 80, we have 25/80 and 12/80. Subtracting 12/80 from 25/80 gives us 13/80 as the result.
80% of 12 = 80% * 12 = 0.8 * 12 = 9.6
12% of 80 = 12% * 80 = 0.12 * 80 = 9.6 or 960%
12 as a percentage of 80 = 100*12/80 = 1200/80 = 15%
