22.5 is what percent of 877 - 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 877 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 877, so we can write it down as 100%=877.
4. We know, that x% equals 22.5 of the output value, so we can write it down as x%=22.5.
5. Now we have two simple equations:
1) 100%=877
2) x%=22.5
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%=877/22.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 22.5 is what percent of 877

100%/x%=877/22.5
(100/x)*x=(877/22.5)*x       - we multiply both sides of the equation by x
100=38.977777777778*x       - we divide both sides of the equation by (38.977777777778) to get x
100/38.977777777778=x
2.5655644241733=x
x=2.5655644241733

now we have:
22.5 is 2.5655644241733% of 877
