2.11 is what percent of 18.8 - 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 18.8 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 18.8, so we can write it down as 100%=18.8.
4. We know, that x% equals 2.11 of the output value, so we can write it down as x%=2.11.
5. Now we have two simple equations:
1) 100%=18.8
2) x%=2.11
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%=18.8/2.11
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.11 is what percent of 18.8

100%/x%=18.8/2.11
(100/x)*x=(18.8/2.11)*x       - we multiply both sides of the equation by x
100=8.9099526066351*x       - we divide both sides of the equation by (8.9099526066351) to get x
100/8.9099526066351=x
11.223404255319=x
x=11.223404255319

now we have:
2.11 is 11.223404255319% of 18.8
