21 is 84 percent of what number? - Answers

21% of 400 = 84 To solve this problem, you can either set up an equation or think it through and save some paper and time. 1. Setup 21 84 --- = --- 100 x 2. Remove denominators (by multiplying both sides by each) 21*x = 100*84 or 21x = 8400 3. Solve for x by dividing each side by 21 x = 8400/21 x = 400 The way I quickly thought through the answer was to consider what 21% means: 21/100. So, the ratio between 21 and 100 needs to be applied to 84. I did this: 100/21 = 4.76 4.76 * 84 = 400 If that's more than you were looking for, sorry, but the answer is 400.
