38.56 is what percent of 1395.2 - 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 1395.2 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 1395.2, so we can write it down as 100%=1395.2.
4. We know, that x% equals 38.56 of the output value, so we can write it down as x%=38.56.
5. Now we have two simple equations:
1) 100%=1395.2
2) x%=38.56
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%=1395.2/38.56
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 38.56 is what percent of 1395.2

100%/x%=1395.2/38.56
(100/x)*x=(1395.2/38.56)*x       - we multiply both sides of the equation by x
100=36.182572614108*x       - we divide both sides of the equation by (36.182572614108) to get x
100/36.182572614108=x
2.7637614678899=x
x=2.7637614678899

now we have:
38.56 is 2.7637614678899% of 1395.2
