1.0E+15 is what percent of 123123123 - 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 123123123 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 123123123, so we can write it down as 100%=123123123.
4. We know, that x% equals 1.0E+15 of the output value, so we can write it down as x%=1.0E+15.
5. Now we have two simple equations:
1) 100%=123123123
2) x%=1.0E+15
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%=123123123/1.0E+15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.0E+15 is what percent of 123123123

100%/x%=123123123/1.0E+15
(100/x)*x=(123123123/1.0E+15)*x       - we multiply both sides of the equation by x
100=1.23123123E-7*x       - we divide both sides of the equation by (1.23123123E-7) to get x
100/1.23123123E-7=x
812195122.76341=x
x=812195122.76341

now we have:
1.0E+15 is 812195122.76341% of 123123123
