Интересно услышать подробности. Вычислить (1 7/9-1 1/3):(1 4/9 +1 1/3-0,5)

(1(7/9) – 1(1/3)) / (1(4/9) + 1(1/3) - 0,5).

1(7/9) – 1(1/3) = 16/9 – 4/3 = 16/9 – 12/9 = 4/9.

(1(4/9) + 1(1/3) - 0,5) = 13/9 + 4/3 – 0,5 = 13/9 + 12/9 – 0,5 = 25/9 – 1/2 = 50/18 – 9/18 = 41/18.

(4/9) / (41/18) = (4/9) * (18/41) = 8/41.

Ответ: 8/41.
