What is 92.8 percent of 20 - 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 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 20 is 100%, so we can write it down as 20=100%.
4. We know, that x is 92.8% of the output value, so we can write it down as x=92.8%.
5. Now we have two simple equations:
1) 20=100%
2) x=92.8%
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:
20/x=100%/92.8%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 92.8% of 20

20/x=100/92.8
(20/x)*x=(100/92.8)*x       - we multiply both sides of the equation by x
20=1.0775862068966*x       - we divide both sides of the equation by (1.0775862068966) to get x
20/1.0775862068966=x
18.56=x
x=18.56

now we have:
92.8% of 20=18.56
