7 is what percent of 18100000 - 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 18100000 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 18100000, so we can write it down as 100%=18100000.
4. We know, that x% equals 7 of the output value, so we can write it down as x%=7.
5. Now we have two simple equations:
1) 100%=18100000
2) x%=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%=18100000/7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7 is what percent of 18100000

100%/x%=18100000/7
(100/x)*x=(18100000/7)*x       - we multiply both sides of the equation by x
100=2585714.2857143*x       - we divide both sides of the equation by (2585714.2857143) to get x
100/2585714.2857143=x
3.8674033149171E-5=x
x=3.8674033149171E-5

now we have:
7 is 3.8674033149171E-5% of 18100000
