272.51 is what percent of 290.51 - 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 290.51 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 290.51, so we can write it down as 100%=290.51.
4. We know, that x% equals 272.51 of the output value, so we can write it down as x%=272.51.
5. Now we have two simple equations:
1) 100%=290.51
2) x%=272.51
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%=290.51/272.51
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 272.51 is what percent of 290.51

100%/x%=290.51/272.51
(100/x)*x=(290.51/272.51)*x       - we multiply both sides of the equation by x
100=1.0660526219221*x       - we divide both sides of the equation by (1.0660526219221) to get x
100/1.0660526219221=x
93.803999862311=x
x=93.803999862311

now we have:
