18.94 is what percent of 30 - 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 30 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 30, so we can write it down as 100%=30.
4. We know, that x% equals 18.94 of the output value, so we can write it down as x%=18.94.
5. Now we have two simple equations:
1) 100%=30
2) x%=18.94
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%=30/18.94
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.94 is what percent of 30

100%/x%=30/18.94
(100/x)*x=(30/18.94)*x       - we multiply both sides of the equation by x
100=1.583949313622*x       - we divide both sides of the equation by (1.583949313622) to get x
100/1.583949313622=x
63.133333333333=x
x=63.133333333333

now we have:
18.94 is 63.133333333333% of 30
