What is 8.3 percent of 109 - 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 109 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 109 is 100%, so we can write it down as 109=100%.
4. We know, that x is 8.3% of the output value, so we can write it down as x=8.3%.
5. Now we have two simple equations:
1) 109=100%
2) x=8.3%
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:
109/x=100%/8.3%
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 8.3% of 109

109/x=100/8.3
(109/x)*x=(100/8.3)*x       - we multiply both sides of the equation by x
109=12.048192771084*x       - we divide both sides of the equation by (12.048192771084) to get x
109/12.048192771084=x
9.047=x
x=9.047

now we have:
8.3% of 109=9.047
