19.79 is what percent of 18.57 - 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 18.57 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 18.57, so we can write it down as 100%=18.57.
4. We know, that x% equals 19.79 of the output value, so we can write it down as x%=19.79.
5. Now we have two simple equations:
1) 100%=18.57
2) x%=19.79
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%=18.57/19.79
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.79 is what percent of 18.57

100%/x%=18.57/19.79
(100/x)*x=(18.57/19.79)*x       - we multiply both sides of the equation by x
100=0.93835270338555*x       - we divide both sides of the equation by (0.93835270338555) to get x
100/0.93835270338555=x
106.56973613355=x
x=106.56973613355

now we have:
19.79 is 106.56973613355% of 18.57
