20 / 0.2 = 100. Therefore, the number that 20 is 20 percent of, is 100.
20/0.2 = 100 Therefore, 20 is 20 percent of 100.
divide the number by the denominator of the fraction 100 / 5 = 20 1/5 of 100 = 20 20 * 5 = 100
100=.20*x100/.20=xx=500
5 x 20 = 100
If the number =x then .2x=answer. --> in words: (20%)*(number)=20% of the number. But percent is (x/y)*100 so you have to divide by 100 to get the number you multiply by; that's why the 20% is 0.2 in the equation.
You take the original number. You then work out by how much this number has changed (so if the new number is bigger subtract the original number from the new number and if it is smaller subtract the new number from the original). Now you divide the difference (how much the number has changed) by the original number and multiply the result by 100.An example:100 becomes 120.The number has changed by (120 - 100) 20. It has increased by 20.To calculate the percentage change we do:20 (the change) / 100 (the original number) and then multiply by 100 (to turn it in to a percentage rather than a fraction).20/100 * 100 = 20%So, in this example, the number has increased by 20%.
100 is 20% of 500
100
375/100 = 3.75 x 20 = 75
10/100 * 20 = 2
100*20 / 60 = 100/3 = 33.333
