90.9 is what percent of 254.1 - 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 254.1 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 254.1, so we can write it down as 100%=254.1.
4. We know, that x% equals 90.9 of the output value, so we can write it down as x%=90.9.
5. Now we have two simple equations:
1) 100%=254.1
2) x%=90.9
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%=254.1/90.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 90.9 is what percent of 254.1

100%/x%=254.1/90.9
(100/x)*x=(254.1/90.9)*x       - we multiply both sides of the equation by x
100=2.7953795379538*x       - we divide both sides of the equation by (2.7953795379538) to get x
100/2.7953795379538=x
35.773317591499=x
x=35.773317591499

now we have:
90.9 is 35.773317591499% of 254.1
