Answer 3

Давайте решим каждое выражение по очереди:

1. (2 + 2/3) * (9/32) * (5 + 1/3) = = (8/3) * (9/32) * (16/3) = = (2/1) * (3/32) * (16/1) = = 3/2 * 3/32 * 16/1 = = 144/64 = = 9/4 = = 2 1/4.

2. (4 + 2/5) * (15/77) * (7/20) = = (22/5) * (15/77) * (7/20) = = (22/1) * (3/77) * (7/1) = = 22/1 * 3/77 * 7/1 = = 462/539 = = 66/77 = = 6/7.

3. (18/25) * (10/27) * (7 + 1/2) = = (18/25) * (10/27) * (15/2) = = (18/25) * (10/27) * (30/4) = = (18/1) * (10/27) * (15/2) = = 18/1 * 10/27 * 15/2 = = 900/54 = = 150/9 = = 16 2/3.

4. (5 + 2/5) * (40/81) * (15/16) = = (27/5) * (40/81) * (15/16) = = (27/1) * (8/81) * (15/4) = = 27/1 * 8/81 * 15/4 = = 2430/1296 = = 135/72 = = 15/8.

5. (6 + 1/4) * (1 + 1/35) * (2 + 1/3) = = (25/4) * (36/35) * (7/3) = = (25/1) * (36/35) * (7/1) = = 25/1 * 36/35 * 7/1 = = 6300/1225 = = 252/49 = = 5 7/49.

6. (12 + 6/7) * (2/25) * (7/18) = = (90/7) * (2/25) * (7/18) = = (90/1) * (2/25) * (1/18) = = 90/1 * 2/25 * 1/18 = = 180/450 = = 2/5.

7. (15/16) * (1 + 13/27) * (2 + 4/25) = = (15/16) * (40/27) * (54/25) = = (15/1) * (40/27) * (54/25) = = 15/1 * 40/27 * 54/25 = = 32400/675 = = 192/5 = = 38 2/5.
