13017.8 is what percent of 21000000000 - 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 21000000000 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 100% equals 21000000000, so we can write it down as 100%=21000000000.
4. We know, that x% equals 13017.8 of the output value, so we can write it down as x%=13017.8.
5. Now we have two simple equations:
1) 100%=21000000000
2) x%=13017.8
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:
100%/x%=21000000000/13017.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13017.8 is what percent of 21000000000

100%/x%=21000000000/13017.8
(100/x)*x=(21000000000/13017.8)*x       - we multiply both sides of the equation by x
100=1613175.8054356*x       - we divide both sides of the equation by (1613175.8054356) to get x
100/1613175.8054356=x
6.1989523809524E-5=x
x=6.1989523809524E-5

now we have:
13017.8 is 6.1989523809524E-5% of 21000000000
