It is 100*(400/80) = 500%
it will be (30*300/100)-(40*400/100)+(50*500/100)=500. hope it will help.
400 000 is 7.2727% of 5 500 000
80% of 500 = 80% * 500 = 0.8 * 500 = 400
find 20 percent of a number, for example: 20% of 500 is 100 then minus the answer off the starting number which is 500. 500 - 100 = 400 400 is 20% off of 500.
Remember that "per cent" just means "out of 100". To find it out of 400, you simply need to multiply by 4.So 12.5 percent x 4 = 50.
8 ÷ 500 is 1.6%.
400 :)
400% increase.
Expressed as a percentage, 400/500 x 100 = 80 percent.
80 x 5 = 400
Take 80% of 500 and you get 400
