136.4 is what percent of 342.7 - 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 342.7 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 342.7, so we can write it down as 100%=342.7.
4. We know, that x% equals 136.4 of the output value, so we can write it down as x%=136.4.
5. Now we have two simple equations:
1) 100%=342.7
2) x%=136.4
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%=342.7/136.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 136.4 is what percent of 342.7

100%/x%=342.7/136.4
(100/x)*x=(342.7/136.4)*x       - we multiply both sides of the equation by x
100=2.5124633431085*x       - we divide both sides of the equation by (2.5124633431085) to get x
100/2.5124633431085=x
39.801575722206=x
x=39.801575722206

now we have:
136.4 is 39.801575722206% of 342.7
