22.2 is what percent of 28.5 - 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 28.5 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 28.5, so we can write it down as 100%=28.5.
4. We know, that x% equals 22.2 of the output value, so we can write it down as x%=22.2.
5. Now we have two simple equations:
1) 100%=28.5
2) x%=22.2
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%=28.5/22.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 22.2 is what percent of 28.5

100%/x%=28.5/22.2
(100/x)*x=(28.5/22.2)*x       - we multiply both sides of the equation by x
100=1.2837837837838*x       - we divide both sides of the equation by (1.2837837837838) to get x
100/1.2837837837838=x
77.894736842105=x
x=77.894736842105

now we have:
22.2 is 77.894736842105% of 28.5
