25.4 is what percent of 115.15 - 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 115.15 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 115.15, so we can write it down as 100%=115.15.
4. We know, that x% equals 25.4 of the output value, so we can write it down as x%=25.4.
5. Now we have two simple equations:
1) 100%=115.15
2) x%=25.4
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%=115.15/25.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 25.4 is what percent of 115.15

100%/x%=115.15/25.4
(100/x)*x=(115.15/25.4)*x       - we multiply both sides of the equation by x
100=4.5334645669291*x       - we divide both sides of the equation by (4.5334645669291) to get x
100/4.5334645669291=x
22.058184976118=x
x=22.058184976118

now we have:
25.4 is 22.058184976118% of 115.15
