180000 is what percent of 8.4E+13 - 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 8.4E+13 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 8.4E+13, so we can write it down as 100%=8.4E+13.
4. We know, that x% equals 180000 of the output value, so we can write it down as x%=180000.
5. Now we have two simple equations:
1) 100%=8.4E+13
2) x%=180000
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%=8.4E+13/180000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 180000 is what percent of 8.4E+13

100%/x%=8.4E+13/180000
(100/x)*x=(8.4E+13/180000)*x       - we multiply both sides of the equation by x
100=466666666.667*x       - we divide both sides of the equation by (466666666.667) to get x
100/466666666.667=x
2.14285714286E-7=x
x=2.14285714286E-7

now we have:
180000 is 2.14285714286E-7% of 8.4E+13
