1 4/9 + 2 6/9 is equal to 4 1/9, true or false?

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.
