503.25 is what percent of 637.86 - 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 637.86 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 637.86, so we can write it down as 100%=637.86.
4. We know, that x% equals 503.25 of the output value, so we can write it down as x%=503.25.
5. Now we have two simple equations:
1) 100%=637.86
2) x%=503.25
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%=637.86/503.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 503.25 is what percent of 637.86

100%/x%=637.86/503.25
(100/x)*x=(637.86/503.25)*x       - we multiply both sides of the equation by x
100=1.2674813710879*x       - we divide both sides of the equation by (1.2674813710879) to get x
100/1.2674813710879=x
78.896623083435=x
x=78.896623083435

now we have:
