To find the percent of anything, you change the percent to a decimal, and multiply. Finding the percent of a sum is no different. ex: 10% of (30 + 100) I can use the distributive property to take 10% of 30, then add 10% of 100. .10(30 + 100) = .10*30 + .10*100 = 3 + 10 = 13 In order to see how this works, let's not distribute. .10(30+100) and instead, add 30 +100 first, then take the percent. .10(130) = 13 We get the same answer! You can take the percent of the whole thing, or you can take the percent of the pieces that add up to the whole.
Well 10 percent of 50 is 5 because you move the decimal point back one. Multiply 6 by the 5, which is 30. 60 percent of 50 is 30. ---- Take a calculator and input 50 multiplied by 60%. You come up with the answer of 30.
Thirty percent For ease of calculation round up 33 to 33.33333 etc Then multiply both by 3 So 10 / 33.33333 is then 30 / 100 or 30%
30%
To find 25 percent of a number, you can multiply the number by 0.25. In this case, we can set up the equation as 0.25x = 30, where x is the unknown number. To solve for x, divide both sides by 0.25, which gives us x = 30 / 0.25 = 120. Therefore, 25 percent of 120 is 30.
