What is 20.8 percent of 3995 - 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 3995 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 3995 is 100%, so we can write it down as 3995=100%.
4. We know, that x is 20.8% of the output value, so we can write it down as x=20.8%.
5. Now we have two simple equations:
1) 3995=100%
2) x=20.8%
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:
3995/x=100%/20.8%
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 20.8% of 3995

3995/x=100/20.8
(3995/x)*x=(100/20.8)*x       - we multiply both sides of the equation by x
3995=4.8076923076923*x       - we divide both sides of the equation by (4.8076923076923) to get x
3995/4.8076923076923=x
830.96=x
x=830.96

now we have:
20.8% of 3995=830.96
