Answer 1

6 2/15 + 42 18/25= 6+42+2/15 +18/25 =48 + 10/75+54/75=48 64/75
5 3/18 + 18 1/27 = 5 + 18 + 3/18 + 1/27 = 23 + 9/54 + 2/54 = 23 11/54
9 3/20 + 7 4/15= 9 + 7 + 3/20 + 4/15 = 16 + 9/60 + 16/60 = 16 25/60=16 5/12
2 19/44 + 5 52/66 = 2 + 5 + 19/44 + 52/66 = 7 + 57/132 + 104/132 =7 161/132
       =7  29/132
38 21/26 + 14 34/39= 38 + 14 +21/26 + 34/39 = 52 + 63/78 + 68/78 = 52 +          =131/78 =52 + 1 53/78 = 53 53/78
6 11/12 + 3 15/16 = 6 + 3 + 11/12+ 15/16 = 9 + 44 /48 + 45/48 = 9 +89/48 =         9 + 1 41/48 = 10  41/48
 
 х - 37 17/18 = 15 16/45
х = 15 16/45 + 37 17/18
х = 15 + 37 + 85/90 + 32/90
х = 52 + 1 3/10
х = 53  3/10

х - 33 21/25 = 42 17/35
х = 42 + 33 + 21/25 + 17/35
х = 75 + 147/175 + 85/175
х = 75 + 1 57/175
х = 76 57/175

4 3/5 + 2 5/7 + 5 9/35 = 4+2+5+ 3/5+ 5/7 + 9/35 = 11 + 21/35 +25/35 +9/35 =    
= 11 + 55/35 = 12 20/35
1 2/3 + 6 4/15 + 8 17/45 = 1+6+8+ 2/3 + 4/15 + 17/45 = 15 + 40/75 + 12/45 + 17/45 = 15 + 69/45 = 16 24/45
