What is 12.6 percent of 1389 - 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 1389 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 1389 is 100%, so we can write it down as 1389=100%.
4. We know, that x is 12.6% of the output value, so we can write it down as x=12.6%.
5. Now we have two simple equations:
1) 1389=100%
2) x=12.6%
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:
1389/x=100%/12.6%
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 12.6% of 1389

1389/x=100/12.6
(1389/x)*x=(100/12.6)*x       - we multiply both sides of the equation by x
1389=7.9365079365079*x       - we divide both sides of the equation by (7.9365079365079) to get x
1389/7.9365079365079=x
175.014=x
x=175.014

now we have:
12.6% of 1389=175.014
