6.4E-5 is what percent of 7700000000 - 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 7700000000 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 7700000000, so we can write it down as 100%=7700000000.
4. We know, that x% equals 6.4E-5 of the output value, so we can write it down as x%=6.4E-5.
5. Now we have two simple equations:
1) 100%=7700000000
2) x%=6.4E-5
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%=7700000000/6.4E-5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.4E-5 is what percent of 7700000000

100%/x%=7700000000/6.4E-5
(100/x)*x=(7700000000/6.4E-5)*x       - we multiply both sides of the equation by x
100=1.203125E+14*x       - we divide both sides of the equation by (1.203125E+14) to get x
100/1.203125E+14=x
8.3116883116883E-13=x
x=8.3116883116883E-13

now we have:
6.4E-5 is 8.3116883116883E-13% of 7700000000
