Пошаговое объяснение:

- 21/2 / 31 / 3 = - 5/2 * 3 / 10 = - 3 / (2 * 2) = - 3/4 =-0,75

- 4 2/3 / (- 11/6) = 14/3 * 6 / 7 = 2 * 2 = 4

3/8 / (- 2 1/4) = 27/8 * (- 4/9) = - 3/2 = - 11/2 =-1,5

71/2 / (3 3/4) = - 15/2 * 4 / 15 = - 2

-5 4/9 / (- 2 1/3) = 49/9 * 3 / 7 = 7/3 = 2 1/3

9 1/3 / (- 6 2/9) = 28/3 * (- 9/56) = - 3/2 = - 11/2 =-1,5
