What is 8.05 percent of 220 - 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 220 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 220 is 100%, so we can write it down as 220=100%.
4. We know, that x is 8.05% of the output value, so we can write it down as x=8.05%.
5. Now we have two simple equations:
1) 220=100%
2) x=8.05%
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:
220/x=100%/8.05%
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 8.05% of 220

220/x=100/8.05
(220/x)*x=(100/8.05)*x       - we multiply both sides of the equation by x
220=12.422360248447*x       - we divide both sides of the equation by (12.422360248447) to get x
220/12.422360248447=x
17.71=x
x=17.71

now we have:
8.05% of 220=17.71
