What is 55.6 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 55.6% of the output value, so we can write it down as x=55.6%.
5. Now we have two simple equations:
1) 20=100%
2) x=55.6%
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:
20/x=100%/55.6%
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 55.6% of 20

20/x=100/55.6
(20/x)*x=(100/55.6)*x       - we multiply both sides of the equation by x
20=1.7985611510791*x       - we divide both sides of the equation by (1.7985611510791) to get x
20/1.7985611510791=x
11.12=x
x=11.12

now we have:
55.6% of 20=11.12
