You can use algebra to find 40% of 20, since that's what I normally do.
Say 100x = 20, as in 100% = 20.
Here we divide both sides by 100, so x = 20/100 = 1/5
This means that 1% of 20 is equal to one fifth.
Then multiply both sides of the equation by 40, so 40x = 40/5 = 8.
Therefore 40% of 20 = 8.
20% is half of 40%.
To find 12.5 percent of a number, multiply the number by 0.125. In this instance, 0.125 x 40 = 5. Therefore, 12.5 percent of 40 is equal to 5.
8/40 x 100 = 20 percent.
8 percent. 20% is one fifth (20/100 = 1/5), and one fifth of 40 is 8, so the answer is 8%.
20% of 200 is 20/100 * 200 = 40 So 200 increased by 20% is 240.
8 / 0.2 = 40 Therefore, the number that 8 is 20 percent of is 40.
20 / 0.5 = 40 Therefore, 20 is 50 percent of 40.
8 / 0.4 = 20 Therefore, 8 is 40 percent of 20.
the percent of a number is when you multiply the percentage by the number, for example: 8% of 40 40 x 0.08= 20% or 20% of 40 0.20 x 40=8%
20 is 40% of 50
40
Divide it. Say you have 20 and want to know what percent of 100 20 is. 20/100= .20 (20 percent) (read percent as parts of 100) You have 100 and you want to know what 40 percent of 100 is? 100 x .40 = 40
8 / 0.2 = 40 Therefore, 20 percent of 40 is 8.
40% of 50% of a number= 40% * 50% of a number= 0.4 * 50% of a number= 20% of a numberor 0.2 of a numberor 1/5 of a number
40 - 20 percent = 820% of 40= 20% * 40= 20%/100% * 40= 8
20/0.5 = 40 x 0.75 = 30 Seventy-five percent of the number is therefore 30.
20 percent of 40 = 0.2 * 40 = 8
