1) (3 3/5 - 2 1/15) 5 = (18/5 - 31/15) 5 = (54/15 - 31/15) 5 = 23/15 5 = 23/3 = 7 2/3
2) (1 14/17 - 1 1/34) 34 = (31/17 - 34/34) 34 = (31/17 - 1) 34 = (31 - 17) 2 = 14 * 34 = 476
3) 8 3/17 5 1/4 + 3 14/17 5 1/4 = (139/17) (21/4) + (59/17) (21/4) = (2929/68) + (1259/68) = 4188/68 = 61 45/68
Итак, значения выражений равны: 7 2/3; 476; 61 45/68.
