It is an increase of 8.88... percent (also an increase of 8 percentage points). 50 &divide; 100 &times; 90 = 45 Note: 50% is a half of something. 50 - 90% = 50 x (1 - (90/100)) = 50 x 0.1 = \$5 Therefore, 90 percent off 50 dollars is equal to 5 dollars. 72 is an increase of negative 20% compared to 90.  90 divided by 2 is same as 50% of 90...anyways it is 45.  50%Since 90 is half of 180, that would be 50%. 50% of a number, X, is 0.50X 54% of a number,X, is 0.54X .54X/.50 X = 1.08 = 8% increase If 47 increases to 97, it increases by 50 units. For 47 units, the increase is 50 units For 1 unit, the increase is 50/47 units For 100 units, the increase is (50/47)(100) = 106.38 % The increase is 90 for a total of 1,890.   50/90 x 100 = 55.5 recurring (that is, 55.5555...) percent.  If 50% of 90 is 50/100 * 90, which equals 45, then 200% of 90 = 200/100 * 90 = 2 * 90 = 180.  180% of 50 = 180% * 50 = 1.8 * 50 = 90 50/12 x 100 - 100 = 316.6 recurring (that is, 316.6666...) percent. The percentage increase is therefore 316.6 recurring percent. 50% is one-half, half of 90 is 45 so your answer is 135.
