The question is poorly phrased because it could mean "20 as a percent of 39" or "20 percent of 39". 20, as a percent of 39 = 100*20/39 = 51.3%
The percent of increase 20 to 39 is: 95%
Percent or percentage equates to hundredths. 39% equates to 39/100' 39% of 20 = 20 x 39/100 = 39/5 = 7.8
Percent Increase = (Final - Initial) / Initial So Percent Increase from 20 to 39 is (39 - 20)/20 19/20, which is 95%
39% x 20 = 7.8
39 over 50 as a percent is 78%
39%
39 over 20 is = 119/20
195%
39/100 = 39%
39/20 = 39 ÷ 20 = 1.95
95 percent increase.
