18.99 is what percent of 20.02 - 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 20.02 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 20.02, so we can write it down as 100%=20.02.
4. We know, that x% equals 18.99 of the output value, so we can write it down as x%=18.99.
5. Now we have two simple equations:
1) 100%=20.02
2) x%=18.99
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%=20.02/18.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.99 is what percent of 20.02

100%/x%=20.02/18.99
(100/x)*x=(20.02/18.99)*x       - we multiply both sides of the equation by x
100=1.0542390731964*x       - we divide both sides of the equation by (1.0542390731964) to get x
100/1.0542390731964=x
94.855144855145=x
x=94.855144855145

now we have:
18.99 is 94.855144855145% of 20.02
