In your problem there are 2 things to consider. The "all" - which in your case is 22. And the "percent of all" - which in your case is 9.
You could think of this as a fraction: 9/22.
So how do you figure out what 9% of 22 is? First, convert 9% into a number. to do that, you move the decimal place back (to the left). So 9% becomes .09. Then multiply this by 22. .09x22= 1.98.
You can check this by estimating. 9% is tough to work with. 10% is easier. 22 is tough to work with, 20 is easier. So 10% of 20 is 2. Since 9 is smaller than 10, you know the answer has to be less than 2!
