What is 12.9 percent of 45000 - 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 45000 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 45000 is 100%, so we can write it down as 45000=100%.
4. We know, that x is 12.9% of the output value, so we can write it down as x=12.9%.
5. Now we have two simple equations:
1) 45000=100%
2) x=12.9%
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:
45000/x=100%/12.9%
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 12.9% of 45000

45000/x=100/12.9
(45000/x)*x=(100/12.9)*x       - we multiply both sides of the equation by x
45000=7.7519379844961*x       - we divide both sides of the equation by (7.7519379844961) to get x
45000/7.7519379844961=x
5805=x
x=5805

now we have:
12.9% of 45000=5805
