What is 31.5 percent of 12500 - 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 12500 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 12500 is 100%, so we can write it down as 12500=100%.
4. We know, that x is 31.5% of the output value, so we can write it down as x=31.5%.
5. Now we have two simple equations:
1) 12500=100%
2) x=31.5%
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:
12500/x=100%/31.5%
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 31.5% of 12500

12500/x=100/31.5
(12500/x)*x=(100/31.5)*x       - we multiply both sides of the equation by x
12500=3.1746031746032*x       - we divide both sides of the equation by (3.1746031746032) to get x
12500/3.1746031746032=x
3937.5=x
x=3937.5

now we have:
31.5% of 12500=3937.5
