$4/9+2/6=8/18+6/18=14/18=7/9$

The first step is to make the denominators (bottom numbers) the same. In this case, the lowest common multiple (LCM) of both 9 and 6 is 18.

To change the $4/9$ to have a denominator of 18, multiply both the numerator (top number) and denominator by 2, so this becomes $8/18$ .

To change the $2/6$ to have a denominator of 18, multiply both the numerator and denominator by 3, so this becomes $6/18$ .

Add the top numbers together and place over the denominator of 18.

$8+6=14$ , to get to $14/18$ . By dividing both the numerator and denominator by 2, you can reduce this answer down to $7/9$ .
