What is 18.45 percent of 39.57 - 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 39.57 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 39.57 is 100%, so we can write it down as 39.57=100%.
4. We know, that x is 18.45% of the output value, so we can write it down as x=18.45%.
5. Now we have two simple equations:
1) 39.57=100%
2) x=18.45%
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:
39.57/x=100%/18.45%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 18.45% of 39.57

39.57/x=100/18.45
(39.57/x)*x=(100/18.45)*x       - we multiply both sides of the equation by x
39.57=5.420054200542*x       - we divide both sides of the equation by (5.420054200542) to get x
39.57/5.420054200542=x
7.300665=x
x=7.300665

now we have:
18.45% of 39.57=7.300665
