What is 31.8 percent of 38642 - 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 38642 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 38642 is 100%, so we can write it down as 38642=100%.
4. We know, that x is 31.8% of the output value, so we can write it down as x=31.8%.
5. Now we have two simple equations:
1) 38642=100%
2) x=31.8%
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:
38642/x=100%/31.8%
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 31.8% of 38642

38642/x=100/31.8
(38642/x)*x=(100/31.8)*x       - we multiply both sides of the equation by x
38642=3.1446540880503*x       - we divide both sides of the equation by (3.1446540880503) to get x
38642/3.1446540880503=x
12288.156=x
x=12288.156

now we have:
31.8% of 38642=12288.156
