А). 91 1/6 + 3 5/18 = 547/6(•3) + 59/18 = 1641/18 + 59/18 = 1700/18 = 94 8/18 = 94 4/9

Б). 1 4/15(•4) + 2 3/20(•3) = 18/15(•4) + 43/20(•2) = 72/60 + 86/60 = 158/60 = 2 38/60 = 2 19/30

В). 5 1/8 + 41 7/12 = 41/8(•3) + 499/12(•2) = 123/24 + 998/24 = 1121/24 = 46 17/24

Г). 39 5/6 + 12 5/9 = 239/6(•3) + 113/9(•2) = 717/18 + 226/18 = 943/18 = 52 13/18

Д). 36 5/7 + 12 7/8 = 257/7(•8) + 103/8(•7) = 2056/56 + 721/56 = 2777/56 = 49 33/56

Е). 5 2/3 + 3/4 = 17/3(•4) + 3/4(•3) = 68/12 + 9/12 = 77/12 = 6 5/12

Ж). 4 + 3 3/7 = 4/1(•7) + 24/7 = 28/7 + 24/7 = 52/7 = 7 3/7

З). 8 7/9 + 3/1 = 79/9 + 3/1(•9) = 79/9 + 27/9 = 106/9 = 11 7/9
