252.15 is what percent of 290 - 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 290 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 290, so we can write it down as 100%=290.
4. We know, that x% equals 252.15 of the output value, so we can write it down as x%=252.15.
5. Now we have two simple equations:
1) 100%=290
2) x%=252.15
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%=290/252.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 252.15 is what percent of 290

100%/x%=290/252.15
(100/x)*x=(290/252.15)*x       - we multiply both sides of the equation by x
100=1.1501090620662*x       - we divide both sides of the equation by (1.1501090620662) to get x
100/1.1501090620662=x
86.948275862069=x
x=86.948275862069

now we have:
252.15 is 86.948275862069% of 290
