Answer 2

Answer:

1 . 12/9

2 . 47/20

3 . 7/4

4 . 19/14

Step-by-step explanation:

1 . 5/9 + 7/9

= (5+7)/9

= 12/9

= 4/3

2 . 3/5 + 7/9

LCM of 5 , 4 is 20

= 12/20 + 35/20

= (12+35)/20

= 47/20

3 . 3/4 + 1

= 3/4 + 4/4

= (3+4)/4

= 7/4

4 . 4/7 + 11/14

LCM of 7 , 14 is 14

= 8/14 + 11/14

= (8+11)/14

= 19/14
