Answer 1

а) 1 1/3 * (8 2/3 : 1 4/9 - 3 3/8 + 1 5/8) – 1 5/6 = 3 5/6

1) 8 2/3 : 1 4/9 = 26/3 : 13/9 = 26/3 * 9/13 = 234/39 = 6

2) 6 – 3 3/8 = 2 5/8

3) 2 5/8 + 1 5/8 = 21/8 + 13/8 = 34/8 = 4 1/4

4) 1 1/3 * 4 1/4 = 4/3 * 17/4 = 68/12 = 5 2/3

5) 5 2/3 – 1 5/6 = 17/3 – 11/6 = 32/6 – 11/6 = 23/6 = 3 5/6

б) ( 3 1/15 – 1 1/15 : 1 3/5 + 2/5) * 2 1/7 - 1 1/7 = 4 6/7

1) 1 1/15 : 1 3/5 = 16/15 : 8/5 = 16/15 * 5/8 = 80/120 = 2/3

2) 3 1/15 - 2/3 = 46/15 - 2/3 = 46/15 - 10/15 = 36/15 = 2 2/5

3) 2 2/5 + 2/5 = 12/5 + 2/5 = 14/5 = 2 4/5

4) 2 4/5 * 2 1/7 = 14/5 * 15/7 = 210/35 = 6

5) 6 – 1 1/7 = 4 6/7
