490.25 is what percent of 575 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 575 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 575, so we can write it down as 100%=575.
4. We know, that x% equals 490.25 of the output value, so we can write it down as x%=490.25.
5. Now we have two simple equations:
1) 100%=575
2) x%=490.25
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=575/490.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 490.25 is what percent of 575

100%/x%=575/490.25
(100/x)*x=(575/490.25)*x       - we multiply both sides of the equation by x
100=1.1728709841917*x       - we divide both sides of the equation by (1.1728709841917) to get x
100/1.1728709841917=x
85.260869565217=x
x=85.260869565217

now we have:
490.25 is 85.260869565217% of 575
