350000 is what percent of 1.4E+16 - 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 1.4E+16 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 1.4E+16, so we can write it down as 100%=1.4E+16.
4. We know, that x% equals 350000 of the output value, so we can write it down as x%=350000.
5. Now we have two simple equations:
1) 100%=1.4E+16
2) x%=350000
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%=1.4E+16/350000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 350000 is what percent of 1.4E+16

100%/x%=1.4E+16/350000
(100/x)*x=(1.4E+16/350000)*x       - we multiply both sides of the equation by x
100=40000000000*x       - we divide both sides of the equation by (40000000000) to get x
100/40000000000=x
2.5E-9=x
x=2.5E-9

now we have:
350000 is 2.5E-9% of 1.4E+16
