Question 542734: how do you solve 63 is 15% of what number?
Answer by lmeeks54(111)   (Show Source):
You can put this solution on YOUR website! Ask the question a different way and the solution may become obvious to you. 63 is 15% of what number is the same as asking, 63 = 15% (or better, .15) * some #. But we always solve with the unknown "some number" on one side of the = sign and everything else on the other.
...
Let x = the unknown #
...
63 = .15 x can be rewritten by dividing both sides by .15
...
x = 63/.15
x = 420 is the answer.
...
check your work by solving for your original question:
420 * .15 = ?
420 * .15 = 63 checks.
...
cheers,
