26.4 is what percent of 402000000000 - 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 402000000000 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 402000000000, so we can write it down as 100%=402000000000.
4. We know, that x% equals 26.4 of the output value, so we can write it down as x%=26.4.
5. Now we have two simple equations:
1) 100%=402000000000
2) x%=26.4
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%=402000000000/26.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 26.4 is what percent of 402000000000

100%/x%=402000000000/26.4
(100/x)*x=(402000000000/26.4)*x       - we multiply both sides of the equation by x
100=15227272727.273*x       - we divide both sides of the equation by (15227272727.273) to get x
100/15227272727.273=x
6.5671641791045E-9=x
x=6.5671641791045E-9

now we have:
26.4 is 6.5671641791045E-9% of 402000000000
