10000000 is what percent of 7.0E+15 - 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 7.0E+15 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 7.0E+15, so we can write it down as 100%=7.0E+15.
4. We know, that x% equals 10000000 of the output value, so we can write it down as x%=10000000.
5. Now we have two simple equations:
1) 100%=7.0E+15
2) x%=10000000
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%=7.0E+15/10000000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 10000000 is what percent of 7.0E+15

100%/x%=7.0E+15/10000000
(100/x)*x=(7.0E+15/10000000)*x       - we multiply both sides of the equation by x
100=700000000*x       - we divide both sides of the equation by (700000000) to get x
100/700000000=x
1.4285714285714E-7=x
x=1.4285714285714E-7

now we have:
10000000 is 1.4285714285714E-7% of 7.0E+15
