17.22 is what percent of 205 - 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 205 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 205, so we can write it down as 100%=205.
4. We know, that x% equals 17.22 of the output value, so we can write it down as x%=17.22.
5. Now we have two simple equations:
1) 100%=205
2) x%=17.22
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%=205/17.22
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.22 is what percent of 205

100%/x%=205/17.22
(100/x)*x=(205/17.22)*x       - we multiply both sides of the equation by x
100=11.904761904762*x       - we divide both sides of the equation by (11.904761904762) to get x
100/11.904761904762=x
8.4=x
x=8.4

now we have:
17.22 is 8.4% of 205
