6.8E-7 is what percent of 3800000000 - 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 3800000000 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 3800000000, so we can write it down as 100%=3800000000.
4. We know, that x% equals 6.8E-7 of the output value, so we can write it down as x%=6.8E-7.
5. Now we have two simple equations:
1) 100%=3800000000
2) x%=6.8E-7
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%=3800000000/6.8E-7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.8E-7 is what percent of 3800000000

100%/x%=3800000000/6.8E-7
(100/x)*x=(3800000000/6.8E-7)*x       - we multiply both sides of the equation by x
100=5.5882352941176E+15*x       - we divide both sides of the equation by (5.5882352941176E+15) to get x
100/5.5882352941176E+15=x
1.7894736842105E-14=x
x=1.7894736842105E-14

now we have:
6.8E-7 is 1.7894736842105E-14% of 3800000000
