20.4 is what percent of 11.2 - 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 11.2 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 11.2, so we can write it down as 100%=11.2.
4. We know, that x% equals 20.4 of the output value, so we can write it down as x%=20.4.
5. Now we have two simple equations:
1) 100%=11.2
2) x%=20.4
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%=11.2/20.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20.4 is what percent of 11.2

100%/x%=11.2/20.4
(100/x)*x=(11.2/20.4)*x       - we multiply both sides of the equation by x
100=0.54901960784314*x       - we divide both sides of the equation by (0.54901960784314) to get x
100/0.54901960784314=x
182.14285714286=x
x=182.14285714286

now we have:
20.4 is 182.14285714286% of 11.2
