What is 3.2 percent of 12500000 - 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 12500000 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 12500000 is 100%, so we can write it down as 12500000=100%.
4. We know, that x is 3.2% of the output value, so we can write it down as x=3.2%.
5. Now we have two simple equations:
1) 12500000=100%
2) x=3.2%
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:
12500000/x=100%/3.2%
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 3.2% of 12500000

12500000/x=100/3.2
(12500000/x)*x=(100/3.2)*x       - we multiply both sides of the equation by x
12500000=31.25*x       - we divide both sides of the equation by (31.25) to get x
12500000/31.25=x
400000=x
x=400000

now we have:
3.2% of 12500000=400000
