What is 38 percent of 20.25 - 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 20.25 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 20.25 is 100%, so we can write it down as 20.25=100%.
4. We know, that x is 38% of the output value, so we can write it down as x=38%.
5. Now we have two simple equations:
1) 20.25=100%
2) x=38%
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:
20.25/x=100%/38%
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% of 20.25

20.25/x=100/38
(20.25/x)*x=(100/38)*x       - we multiply both sides of the equation by x
20.25=2.6315789473684*x       - we divide both sides of the equation by (2.6315789473684) to get x
20.25/2.6315789473684=x
7.695=x
x=7.695

now we have:
38% of 20.25=7.695
