Answer 1

3/4+4/3 = (9 + 16) /12 = 25/12

5/2+2/3= (15 + 4) /6 = 19/6

8/9+4/3 = (8 + 12 ) /9 = 20/9

6/11+5/22 = (12 + 5 ) /22 = 17/22

7/14+14/9 =1/2 + 14/9 = (9 + 28) /18 = 37/18

5/12+3/4 = (5+9) /12 = 14/12

11/14+7/22 = (121+49) /154= 170/154 = 85/77

3/8+5/6 =(18 + 40) /48= 58/48 = 29/24

19/21+38/7 = (19+114) /21 = 133/21 = 19/3
