Answer: True
Explanation: To add mixed numbers, first add the fractions.
So here, we have 4/9 + 6/9 which is 10/9.
Then add the whole numbers.
So we have 1 + 2 which is 3.
So our answer is 3 and 10/9.
But notice, that since 10/9 is an improper fraction,
our answer is not in lowest terms.
10/9 can be rewritten as the mixed number 1 and 1/9.
So 3 and 10/9 is the same as 3 + 1 and 1/9 which is 4 and 1/9.
Since 4 and 1/9 is in lowest terms, this is our final answer.
So we can say that 1 and 4/9 + 2 and 6/9 is 4 and 1/9.
