What is 21000000 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 21000000% of the output value, so we can write it down as x=21000000%.
5. Now we have two simple equations:
1) 12500=100%
2) x=21000000%
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%/21000000%
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 21000000% of 12500

12500/x=100/21000000
(12500/x)*x=(100/21000000)*x       - we multiply both sides of the equation by x
12500=4.7619047619048E-6*x       - we divide both sides of the equation by (4.7619047619048E-6) to get x
12500/4.7619047619048E-6=x
2625000000=x
x=2625000000

now we have:
21000000% of 12500=2625000000
