Sarah lived in Rochester for 8 years. 1/9 of 18 is 2. If you have 4/9 then you would do two times 4. That's how I did it because it was 18 and 9 can go into 18. Normally the way to do these problems is to solve 4/9x18/1. If the problem has a fraction and says of, you would multiply the fraction by the whole number. In this case, 4/9 and 18.
