7 is what percent of 18800 - 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 18800 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 18800, so we can write it down as 100%=18800.
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%=18800
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%=18800/7
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 18800

100%/x%=18800/7
(100/x)*x=(18800/7)*x       - we multiply both sides of the equation by x
100=2685.7142857143*x       - we divide both sides of the equation by (2685.7142857143) to get x
100/2685.7142857143=x
0.037234042553191=x
x=0.037234042553191

now we have:
7 is 0.037234042553191% of 18800
