135.85 is what percent of 339.4 - 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 339.4 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 339.4, so we can write it down as 100%=339.4.
4. We know, that x% equals 135.85 of the output value, so we can write it down as x%=135.85.
5. Now we have two simple equations:
1) 100%=339.4
2) x%=135.85
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%=339.4/135.85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 135.85 is what percent of 339.4

100%/x%=339.4/135.85
(100/x)*x=(339.4/135.85)*x       - we multiply both sides of the equation by x
100=2.4983437615017*x       - we divide both sides of the equation by (2.4983437615017) to get x
100/2.4983437615017=x
40.026517383618=x
x=40.026517383618

now we have:
135.85 is 40.026517383618% of 339.4
