What is 38.9 percent of 83 - 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 83 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 83 is 100%, so we can write it down as 83=100%.
4. We know, that x is 38.9% of the output value, so we can write it down as x=38.9%.
5. Now we have two simple equations:
1) 83=100%
2) x=38.9%
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:
83/x=100%/38.9%
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 38.9% of 83

83/x=100/38.9
(83/x)*x=(100/38.9)*x       - we multiply both sides of the equation by x
83=2.5706940874036*x       - we divide both sides of the equation by (2.5706940874036) to get x
83/2.5706940874036=x
32.287=x
x=32.287

now we have:
38.9% of 83=32.287
