337.4 is what percent of 415 - 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 415 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 415, so we can write it down as 100%=415.
4. We know, that x% equals 337.4 of the output value, so we can write it down as x%=337.4.
5. Now we have two simple equations:
1) 100%=415
2) x%=337.4
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%=415/337.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 337.4 is what percent of 415

100%/x%=415/337.4
(100/x)*x=(415/337.4)*x       - we multiply both sides of the equation by x
100=1.2299940723177*x       - we divide both sides of the equation by (1.2299940723177) to get x
100/1.2299940723177=x
81.301204819277=x
x=81.301204819277

now we have:
337.4 is 81.301204819277% of 415
