What is 12.99 percent of 117 - 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 117 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 117 is 100%, so we can write it down as 117=100%.
4. We know, that x is 12.99% of the output value, so we can write it down as x=12.99%.
5. Now we have two simple equations:
1) 117=100%
2) x=12.99%
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:
117/x=100%/12.99%
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 12.99% of 117

117/x=100/12.99
(117/x)*x=(100/12.99)*x       - we multiply both sides of the equation by x
117=7.6982294072363*x       - we divide both sides of the equation by (7.6982294072363) to get x
117/7.6982294072363=x
15.1983=x
x=15.1983

now we have:
12.99% of 117=15.1983
