22.5 is what percent of 250.4 - 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 250.4 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 250.4, so we can write it down as 100%=250.4.
4. We know, that x% equals 22.5 of the output value, so we can write it down as x%=22.5.
5. Now we have two simple equations:
1) 100%=250.4
2) x%=22.5
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%=250.4/22.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 22.5 is what percent of 250.4

100%/x%=250.4/22.5
(100/x)*x=(250.4/22.5)*x       - we multiply both sides of the equation by x
100=11.128888888889*x       - we divide both sides of the equation by (11.128888888889) to get x
100/11.128888888889=x
8.9856230031949=x
x=8.9856230031949

now we have:
22.5 is 8.9856230031949% of 250.4
