3.68 is what percent of 18 - 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 18 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 18, so we can write it down as 100%=18.
4. We know, that x% equals 3.68 of the output value, so we can write it down as x%=3.68.
5. Now we have two simple equations:
1) 100%=18
2) x%=3.68
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%=18/3.68
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.68 is what percent of 18

100%/x%=18/3.68
(100/x)*x=(18/3.68)*x       - we multiply both sides of the equation by x
100=4.8913043478261*x       - we divide both sides of the equation by (4.8913043478261) to get x
100/4.8913043478261=x
20.444444444444=x
x=20.444444444444

now we have:
3.68 is 20.444444444444% of 18
