№1
1) 3 1/9 : 2 1/3 = 28/9 : 7/3 = 28/9 * 3/7 = 4/3 * 1/1 = 4/3 = 1 1/3
2) 1 1/3 - 2 5/6 = 1 2/6 - 2 5/6 = -1 3/6 = -1 1/2
№2
1) 4 3/13 : 1 19/26 = 55/13 : 45/26 = 55/13 * 26/45 = 11/1 * 2/9 = 22/9 = 2 4/9
2) 1 5/7 - 2 4/9 = 1 45/63 - 2 28/63 = 1 45/63 - 1 81/63 = -36/63 = -4/7
№3
1) 10 16/17 : 8 5/11 = 186/17 : 93/11 = 186/17 * 11/93 = 2/17 * 11/1 = 22/17 = 1 5/17
2) 1 5/17 + 1 2/3 = 1 15/51 + 1 34/51 = 2 49/51
№4
1) 47/48 : 3 13/27 = 47/48 : 94/27 = 47/48 * 27/94 = 1/16 * 9/2 = 9/32
2) 9/32 - 13/16 = 9/32 - 26/32 = -17/32
