20 is what percent of 239.94 - 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 239.94 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 239.94, so we can write it down as 100%=239.94.
4. We know, that x% equals 20 of the output value, so we can write it down as x%=20.
5. Now we have two simple equations:
1) 100%=239.94
2) x%=20
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%=239.94/20
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20 is what percent of 239.94

100%/x%=239.94/20
(100/x)*x=(239.94/20)*x       - we multiply both sides of the equation by x
100=11.997*x       - we divide both sides of the equation by (11.997) to get x
100/11.997=x
8.3354171876302=x
x=8.3354171876302

now we have:
20 is 8.3354171876302% of 239.94
