917.72 is what percent of 20000 - 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 20000 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 20000, so we can write it down as 100%=20000.
4. We know, that x% equals 917.72 of the output value, so we can write it down as x%=917.72.
5. Now we have two simple equations:
1) 100%=20000
2) x%=917.72
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%=20000/917.72
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 917.72 is what percent of 20000

100%/x%=20000/917.72
(100/x)*x=(20000/917.72)*x       - we multiply both sides of the equation by x
100=21.793139519679*x       - we divide both sides of the equation by (21.793139519679) to get x
100/21.793139519679=x
4.5886=x
x=4.5886

now we have:
917.72 is 4.5886% of 20000
