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.
