39 is 19 more than 20, so the percentage increase can be determined by dividing 20 by 19. the answer therefore is "to get from 20 to 39, you increase it by 95%" or "39 is 195% of 20". the second answer was obtained because it is including the original value (100%) and adding the extra value to show increase.
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 20 = 195%
195%
95 percent increase.
Well, honey, that's a 95% increase. So, basically, you went from 20 to 39, which is a jump of 19. Divide that by the original number (20) and multiply by 100 to get your percentage. Voila, math magic!
95% increase
20% of 195= 20% * 195= 0.2 * 195= 39
100*(39-20)/20 = 100*19/20 = 95%100*(39-20)/20 = 100*19/20 = 95%100*(39-20)/20 = 100*19/20 = 95%100*(39-20)/20 = 100*19/20 = 95%
