22.5 is what percent of 28.75 - 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 28.75 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 28.75, so we can write it down as 100%=28.75.
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%=28.75
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%=28.75/22.5
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 28.75

100%/x%=28.75/22.5
(100/x)*x=(28.75/22.5)*x       - we multiply both sides of the equation by x
100=1.2777777777778*x       - we divide both sides of the equation by (1.2777777777778) to get x
100/1.2777777777778=x
78.260869565217=x
x=78.260869565217

now we have:
22.5 is 78.260869565217% of 28.75
