Answer 2

1) (3/22 + 2/11) × 2 = (6/22 + 4/11) × 2 = (12/22 + 8/22) × 2 = 20/22 × 2 = 40/22 = 20/11

2) (3/5 - 1 + 2/3) : 16 = (9/15 - 15/15 + 10/15) : 16 = 4/15 : 16 = 4/15 × 1/16 = 4/240 = 1/60

3) (4 + 1/9 - 5) × 5/8 = (36/9 + 1/9 - 45/9) × 5/8 = (37/9 - 45/9) × 5/8 = -8/9 × 5/8 = -40/72 = -5/9

4) 1/23 × (5/6 + 4/9) = 1/23 × (15/18 + 8/18) = 1/23 × 23/18 = 1/18

5) (8/25 - 22/75) : 2/5 = (24/75 - 22/75) : 2/5 = 2/75 : 2/5 = 2/75 × 5/2 = 10/150 = 1/15

6) (1/11 + 1/3) × 3/7 = (3/33 + 11/33) × 3/7 = 14/33 × 3/7 = 42/231 = 6/33 = 2/11

Таким образом, ответы для данных выражений следующие: 1) 20/11 2) 1/60 3) -5/9 4) 1/18 5) 1/15 6) 2/11
