21.85 is what percent of 106 - 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 106 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 106, so we can write it down as 100%=106.
4. We know, that x% equals 21.85 of the output value, so we can write it down as x%=21.85.
5. Now we have two simple equations:
1) 100%=106
2) x%=21.85
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%=106/21.85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.85 is what percent of 106

100%/x%=106/21.85
(100/x)*x=(106/21.85)*x       - we multiply both sides of the equation by x
100=4.8512585812357*x       - we divide both sides of the equation by (4.8512585812357) to get x
100/4.8512585812357=x
20.61320754717=x
x=20.61320754717

now we have:
21.85 is 20.61320754717% of 106
