Question 1062194: What number minus 10% equals 700?
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! let x be the number.
10% of x is equal to .10x
you have x - .10x = 700
combine like terms to get .9x = 700
divide both sides of this equation by .9 to get x = 700/.9 which is equal to 777.77777778.
that's the number that you're looking for.
how do you know this is true?
take 777.77777778 and subtract 10% of that to see what you get.
777.77777778 = 77.77777778 is equal to 700.
unless you store the intermediate results in your calculator, you might get some rounding errors.
if they're there, they should be minimal.
