18.1 is what percent of 900 - 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 900 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 900, so we can write it down as 100%=900.
4. We know, that x% equals 18.1 of the output value, so we can write it down as x%=18.1.
5. Now we have two simple equations:
1) 100%=900
2) x%=18.1
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%=900/18.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.1 is what percent of 900

100%/x%=900/18.1
(100/x)*x=(900/18.1)*x       - we multiply both sides of the equation by x
100=49.723756906077*x       - we divide both sides of the equation by (49.723756906077) to get x
100/49.723756906077=x
2.0111111111111=x
x=2.0111111111111

now we have:
18.1 is 2.0111111111111% of 900
