12.2 is what percent of 253.4 - 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 253.4 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 253.4, so we can write it down as 100%=253.4.
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%=253.4
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%=253.4/12.2
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 253.4

100%/x%=253.4/12.2
(100/x)*x=(253.4/12.2)*x       - we multiply both sides of the equation by x
100=20.770491803279*x       - we divide both sides of the equation by (20.770491803279) to get x
100/20.770491803279=x
4.8145224940805=x
x=4.8145224940805

now we have:
12.2 is 4.8145224940805% of 253.4
