Пошаговое объяснение:
1)
-7целых 1/2 ÷ (-5) = -15/2 × (-1/5) = -3/2 × (-1/1) = 3/2 = 1целая 1/2 или 1,5
2)
-8целых 2/5 ÷ 7 = -42/5 × 1/7 = -6/5 × 1/1 = -6/5 = -1целая 1/5 или -1,2
3)
-11целых 1/5 ÷ 8 = -56/5 × 1/8 = -7/5 × 1/1 = - 7/5 = -1целая 2/5 или -1,4
4)
13целых 4/5 ÷ (-6) = 69/5 × (-1/6) = 23/5 × (-1/2) = -23/10 = -2целых 3/10 и -2,3
5)
-7целых 3/5 ÷ (-4) = -38/5 × (-1/4) =-19/5 × (-1/2) = 19/10 = 1целая 9/10 или 1,9
6)
-18целых 3/4 ÷ (-3) = -75/4 × (-1/3) = -25/4 × (-1/1) = 25/4 = 6целых 1/4
