20 is what percent of 8765 - 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 8765 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 8765, so we can write it down as 100%=8765.
4. We know, that x% equals 20 of the output value, so we can write it down as x%=20.
5. Now we have two simple equations:
1) 100%=8765
2) x%=20
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%=8765/20
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20 is what percent of 8765

100%/x%=8765/20
(100/x)*x=(8765/20)*x       - we multiply both sides of the equation by x
100=438.25*x       - we divide both sides of the equation by (438.25) to get x
100/438.25=x
0.2281802624073=x
x=0.2281802624073

now we have:
20 is 0.2281802624073% of 8765
