Answer:
Tom; 2/9 more
Step-by-step explanation:
To compare fractions, they need to have a common denominator. We get this by multiplying the fractions least common multiple of the denominators. So:
the LCM of 9 and 3 is 9.
Multiply 2/3 by 3/3 to get 6/9
8/9 already has 9 as a denominator
8/9 is more than 6/9, so Tom ate more. 8-6 is 2, so he ate 2/9 of a pie more.
