621.83 is what percent of 1540.5 - 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 1540.5 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 1540.5, so we can write it down as 100%=1540.5.
4. We know, that x% equals 621.83 of the output value, so we can write it down as x%=621.83.
5. Now we have two simple equations:
1) 100%=1540.5
2) x%=621.83
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%=1540.5/621.83
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 621.83 is what percent of 1540.5

100%/x%=1540.5/621.83
(100/x)*x=(1540.5/621.83)*x       - we multiply both sides of the equation by x
100=2.4773651962755*x       - we divide both sides of the equation by (2.4773651962755) to get x
100/2.4773651962755=x
40.365465757871=x
x=40.365465757871

now we have:
