What is 22 percent of 9 - 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 9 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 9 is 100%, so we can write it down as 9=100%.
4. We know, that x is 22% of the output value, so we can write it down as x=22%.
5. Now we have two simple equations:
1) 9=100%
2) x=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:
9/x=100%/22%
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 22% of 9

9/x=100/22
(9/x)*x=(100/22)*x       - we multiply both sides of the equation by x
9=4.5454545454545*x       - we divide both sides of the equation by (4.5454545454545) to get x
9/4.5454545454545=x
1.98=x
x=1.98

now we have:
22% of 9=1.98
