400 is what percent of 500:= 400 / 500= 0.8Converting decimal to a percentage: 0.8 * 100 = 80%
100 / 500 = 0.2500 * 0.2 = 100
It is 100*(400/80) = 500%
400 C = 100 and D = 500 and when arranged as CD or CD this means 500-100 = 400
XVXVXAnother answer:400 in Roman numerals is CD (-100+500 = 400) but 100-1400=400 still because the numeral ups one after subtraction so actually(-100+500 = 400) doesn't exist
400 is what percent of 500:= 400 / 500= 0.8Converting decimal to a percentage: 0.8 * 100 = 80%
100 + 400 = 500
125%% rate:= 500/400 * 100%= 1.25 * 100%= 125%
400
The hundreds, on either side of 449 are 400 and 500. 449 is 49 away from 400, and 51 away from 500. So the nearest hundred is 400.
It is 3000 because 400 is less than 500
500 - 5x = 100 500 = 100 + 5x 400 = 5x x = 80 Check it. -400 + 500 = 100 It checks.
100 + 300 + 500 + 500 + 600 = 2000. Then divide by 5 to get 400. The mean of these five numbers is 400.
$500.If you increase something by 400% then you are making it 5 times larger.So if $100 is increased by 400% this equals $100 times 5 = $500.In terms of the easiest steps possible to understand the principle here, you could also work this out by:*finding out what 100% of the value is.*multiplying this by 4 (as we have 400%)*adding this to the original amount (as we are increasing by 400%)100% of $100 = $100$100 * 4 = $400$400 + $100 = $500
100 / 500 = 0.2500 * 0.2 = 100
400
It is 100*(400/80) = 500%
