6 is what percent of 20.99 - 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 20.99 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 20.99, so we can write it down as 100%=20.99.
4. We know, that x% equals 6 of the output value, so we can write it down as x%=6.
5. Now we have two simple equations:
1) 100%=20.99
2) x%=6
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%=20.99/6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6 is what percent of 20.99

100%/x%=20.99/6
(100/x)*x=(20.99/6)*x       - we multiply both sides of the equation by x
100=3.4983333333333*x       - we divide both sides of the equation by (3.4983333333333) to get x
100/3.4983333333333=x
28.585040495474=x
x=28.585040495474

now we have:
6 is 28.585040495474% of 20.99
