20450 is what percent of 22815 - 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 22815 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 22815, so we can write it down as 100%=22815.
4. We know, that x% equals 20450 of the output value, so we can write it down as x%=20450.
5. Now we have two simple equations:
1) 100%=22815
2) x%=20450
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%=22815/20450
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20450 is what percent of 22815

100%/x%=22815/20450
(100/x)*x=(22815/20450)*x       - we multiply both sides of the equation by x
100=1.1156479217604*x       - we divide both sides of the equation by (1.1156479217604) to get x
100/1.1156479217604=x
89.634012710936=x
x=89.634012710936

now we have:
20450 is 89.634012710936% of 22815
