What is 8.15 percent of 9930 - 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 9930 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 9930 is 100%, so we can write it down as 9930=100%.
4. We know, that x is 8.15% of the output value, so we can write it down as x=8.15%.
5. Now we have two simple equations:
1) 9930=100%
2) x=8.15%
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:
9930/x=100%/8.15%
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 8.15% of 9930

9930/x=100/8.15
(9930/x)*x=(100/8.15)*x       - we multiply both sides of the equation by x
9930=12.269938650307*x       - we divide both sides of the equation by (12.269938650307) to get x
9930/12.269938650307=x
809.295=x
x=809.295

now we have:
8.15% of 9930=809.295
