137.17 is what percent of 840 - 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 840 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 840, so we can write it down as 100%=840.
4. We know, that x% equals 137.17 of the output value, so we can write it down as x%=137.17.
5. Now we have two simple equations:
1) 100%=840
2) x%=137.17
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%=840/137.17
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 137.17 is what percent of 840

100%/x%=840/137.17
(100/x)*x=(840/137.17)*x       - we multiply both sides of the equation by x
100=6.1237880002916*x       - we divide both sides of the equation by (6.1237880002916) to get x
100/6.1237880002916=x
16.329761904762=x
x=16.329761904762

now we have:
137.17 is 16.329761904762% of 840
