What is 12.9 percent of 582 - 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 582 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 582 is 100%, so we can write it down as 582=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) 582=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:
582/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 582

582/x=100/12.9
(582/x)*x=(100/12.9)*x       - we multiply both sides of the equation by x
582=7.7519379844961*x       - we divide both sides of the equation by (7.7519379844961) to get x
582/7.7519379844961=x
75.078=x
x=75.078

now we have:
12.9% of 582=75.078
