What is 38.11 percent of 20 - 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 20 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 20 is 100%, so we can write it down as 20=100%.
4. We know, that x is 38.11% of the output value, so we can write it down as x=38.11%.
5. Now we have two simple equations:
1) 20=100%
2) x=38.11%
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:
20/x=100%/38.11%
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 38.11% of 20

20/x=100/38.11
(20/x)*x=(100/38.11)*x       - we multiply both sides of the equation by x
20=2.6239832065075*x       - we divide both sides of the equation by (2.6239832065075) to get x
20/2.6239832065075=x
7.622=x
x=7.622

now we have:
38.11% of 20=7.622
