27.4 is what percent of 12.2 - 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 12.2 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 12.2, so we can write it down as 100%=12.2.
4. We know, that x% equals 27.4 of the output value, so we can write it down as x%=27.4.
5. Now we have two simple equations:
1) 100%=12.2
2) x%=27.4
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%=12.2/27.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 27.4 is what percent of 12.2

100%/x%=12.2/27.4
(100/x)*x=(12.2/27.4)*x       - we multiply both sides of the equation by x
100=0.44525547445255*x       - we divide both sides of the equation by (0.44525547445255) to get x
100/0.44525547445255=x
224.59016393443=x
x=224.59016393443

now we have:
27.4 is 224.59016393443% of 12.2
