What is 125 percent of 12780 - 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 12780 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 12780 is 100%, so we can write it down as 12780=100%.
4. We know, that x is 125% of the output value, so we can write it down as x=125%.
5. Now we have two simple equations:
1) 12780=100%
2) x=125%
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:
12780/x=100%/125%
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 125% of 12780

12780/x=100/125
(12780/x)*x=(100/125)*x       - we multiply both sides of the equation by x
12780=0.8*x       - we divide both sides of the equation by (0.8) to get x
12780/0.8=x
15975=x
x=15975

now we have:
125% of 12780=15975
