Ответ:

5 -> 2 4/7 -> 2 -> 1 1/2 -> 17/27 -> 1/6 -> 10/9

Пошаговое объяснение:

5 = 4 7/7 => 4 7/7 - 2 3/7 = 2 4/7

2 4/7 = 18/7 & 1 2/7 = 9/7 => 18/7 ÷ 9/7 = 18/7 x 7/9 = 2

2 = 6/3 & 1 1/3 = 4/3 => 6/3 ÷ 4/3 = 6/3 x 3/4 = 3/2 = 1 1/2

17/18 ÷ 3/2 = 17/18 x 2/3 = 17/27

5 = 45/9 => 45/9 x 2/9 = 90/81 = 10/9

10/9 - 17/18 = 20/18 - 17/18 = 3/18 = 1/6
