What is 12.875 percent of 159 - 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 159 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 159 is 100%, so we can write it down as 159=100%.
4. We know, that x is 12.875% of the output value, so we can write it down as x=12.875%.
5. Now we have two simple equations:
1) 159=100%
2) x=12.875%
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:
159/x=100%/12.875%
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 12.875% of 159

159/x=100/12.875
(159/x)*x=(100/12.875)*x       - we multiply both sides of the equation by x
159=7.7669902912621*x       - we divide both sides of the equation by (7.7669902912621) to get x
159/7.7669902912621=x
20.47125=x
x=20.47125

now we have:
12.875% of 159=20.47125
