16.99 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 16.99 of the output value, so we can write it down as x%=16.99.
5. Now we have two simple equations:
1) 100%=18
2) x%=16.99
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%=18/16.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 16.99 is what percent of 18

100%/x%=18/16.99
(100/x)*x=(18/16.99)*x       - we multiply both sides of the equation by x
100=1.0594467333726*x       - we divide both sides of the equation by (1.0594467333726) to get x
100/1.0594467333726=x
94.388888888889=x
x=94.388888888889

now we have:
16.99 is 94.388888888889% of 18
