(13 1/6-15):(-2,2+1 1/3)

2 целых и  3/26

Пошаговое объяснение:

(13 1/6-15):(-2,2+1 1/3) = (79/6 - 15) : (-22/10 +4/3) = (79/6 - 90/6) : (- 66/30 + 40/30) = -11/6 : - 26/30 = 55/30 * 30/26 = 55/26 = 2  3/26

2. 3/26

Пошаговое объяснение:

1) 13. 1/6 - 15 =

13. 1/6 - 14. 6/6 = -1. 5/6

2) -2,2 + 1. 1/3 =

-2. 2/10 + 1. 1/3 =

-2. 6/30 + 1. 10/30 =

-1. 36/30 + 1. 10/30 =

-26/30 = -13/15

3) -1. 5/6 : (-13/15) =

-11/6 * (-15/13) = -11/2 * (-5/13) = 55/26 = 2. 3/26
