What is 8.02 percent of 3.99 - 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 3.99 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 3.99 is 100%, so we can write it down as 3.99=100%.
4. We know, that x is 8.02% of the output value, so we can write it down as x=8.02%.
5. Now we have two simple equations:
1) 3.99=100%
2) x=8.02%
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:
3.99/x=100%/8.02%
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 8.02% of 3.99

3.99/x=100/8.02
(3.99/x)*x=(100/8.02)*x       - we multiply both sides of the equation by x
3.99=12.468827930175*x       - we divide both sides of the equation by (12.468827930175) to get x
3.99/12.468827930175=x
0.319998=x
x=0.319998

now we have:
8.02% of 3.99=0.319998
