137.3 is what percent of 620 - 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 620 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 620, so we can write it down as 100%=620.
4. We know, that x% equals 137.3 of the output value, so we can write it down as x%=137.3.
5. Now we have two simple equations:
1) 100%=620
2) x%=137.3
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%=620/137.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 137.3 is what percent of 620

100%/x%=620/137.3
(100/x)*x=(620/137.3)*x       - we multiply both sides of the equation by x
100=4.5156591405681*x       - we divide both sides of the equation by (4.5156591405681) to get x
100/4.5156591405681=x
22.145161290323=x
x=22.145161290323

now we have:
137.3 is 22.145161290323% of 620
