What is 9.02 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 9.02% of the output value, so we can write it down as x=9.02%.
5. Now we have two simple equations:
1) 3.99=100%
2) x=9.02%
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%/9.02%
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 9.02% of 3.99

3.99/x=100/9.02
(3.99/x)*x=(100/9.02)*x       - we multiply both sides of the equation by x
3.99=11.086474501109*x       - we divide both sides of the equation by (11.086474501109) to get x
3.99/11.086474501109=x
0.359898=x
x=0.359898

now we have:
9.02% of 3.99=0.359898
