What is 91.2 percent of 38 - 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 38 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 38 is 100%, so we can write it down as 38=100%.
4. We know, that x is 91.2% of the output value, so we can write it down as x=91.2%.
5. Now we have two simple equations:
1) 38=100%
2) x=91.2%
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:
38/x=100%/91.2%
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 91.2% of 38

38/x=100/91.2
(38/x)*x=(100/91.2)*x       - we multiply both sides of the equation by x
38=1.0964912280702*x       - we divide both sides of the equation by (1.0964912280702) to get x
38/1.0964912280702=x
34.656=x
x=34.656

now we have:
91.2% of 38=34.656
