12.2 is what percent of 27.5 - 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 27.5 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 27.5, so we can write it down as 100%=27.5.
4. We know, that x% equals 12.2 of the output value, so we can write it down as x%=12.2.
5. Now we have two simple equations:
1) 100%=27.5
2) x%=12.2
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%=27.5/12.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.2 is what percent of 27.5

100%/x%=27.5/12.2
(100/x)*x=(27.5/12.2)*x       - we multiply both sides of the equation by x
100=2.2540983606557*x       - we divide both sides of the equation by (2.2540983606557) to get x
100/2.2540983606557=x
44.363636363636=x
x=44.363636363636

now we have:
12.2 is 44.363636363636% of 27.5
