Answer 1

547/6 +59/18 = (1641 + 59)/18 = 1700/18 = 94  8/18 = 94  4/9

19/15 + 42/20 = (76 + 126) / 60 = 202/60 = 3  11/30

239/6 + 113/9 = (717 +226) /18 = 943/18 = 52  7/18

257/7 + 103/8 = ( 2056 + 721) /56 = 2777/56 = 49  33/56

17/3 + 3/4 = (68 + 6) / 12 = 74/12 = 6  1/6

4 + 3 3/7 = 7  3/7

8  7/9 + 3 = 11  7/9
