What is 38.8 percent of 809.3 - 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 809.3 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 809.3 is 100%, so we can write it down as 809.3=100%.
4. We know, that x is 38.8% of the output value, so we can write it down as x=38.8%.
5. Now we have two simple equations:
1) 809.3=100%
2) x=38.8%
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:
809.3/x=100%/38.8%
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 38.8% of 809.3

809.3/x=100/38.8
(809.3/x)*x=(100/38.8)*x       - we multiply both sides of the equation by x
809.3=2.5773195876289*x       - we divide both sides of the equation by (2.5773195876289) to get x
809.3/2.5773195876289=x
314.0084=x
x=314.0084

now we have:
38.8% of 809.3=314.0084
