What is 14 percent of 129.86 - 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 129.86 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 129.86 is 100%, so we can write it down as 129.86=100%.
4. We know, that x is 14% of the output value, so we can write it down as x=14%.
5. Now we have two simple equations:
1) 129.86=100%
2) x=14%
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:
129.86/x=100%/14%
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 14% of 129.86

129.86/x=100/14
(129.86/x)*x=(100/14)*x       - we multiply both sides of the equation by x
129.86=7.1428571428571*x       - we divide both sides of the equation by (7.1428571428571) to get x
129.86/7.1428571428571=x
18.1804=x
x=18.1804

now we have:
14% of 129.86=18.1804
