What is 4000000 percent of 13000000 - 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 13000000 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 13000000 is 100%, so we can write it down as 13000000=100%.
4. We know, that x is 4000000% of the output value, so we can write it down as x=4000000%.
5. Now we have two simple equations:
1) 13000000=100%
2) x=4000000%
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:
13000000/x=100%/4000000%
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 4000000% of 13000000

13000000/x=100/4000000
(13000000/x)*x=(100/4000000)*x       - we multiply both sides of the equation by x
13000000=2.5E-5*x       - we divide both sides of the equation by (2.5E-5) to get x
13000000/2.5E-5=x
520000000000=x
x=520000000000

now we have:
4000000% of 13000000=520000000000
