Ответ:
-1/9
Пошаговое объяснение:
1) -3 1/3 * 1,9 = -10/3 * 19/10 = - 19/3 = -6 1/3
2) 19,5 : 4 1/3 = 195/10 * 3/13 = 15/2 = 7 1/2
3) -6 1/3 + 7 1/2 = 1/2 - 1/3 = 1/6
4) 0.16 - 62/75 = 16/100 - 62/75 = 4/25 - 62/75 = -50/75 = - 2/3
5) 1/6 : (-2/3) = -1/6 * 2/3 = -1/9
1) -3. 1/3 * 1,9 = -10/3 * 19/10 = -19/3 = -6. 1/3
2) 19,5 : 4. 1/3 = 195/10 : 13/3 = 195/10 * 3/13 = 15/10 * 3/1 = 45/10 = 4. 5/10 = 4. 1/2
3) -6. 1/3 + 4. 1/2 = -6. 2/6 + 4. 3/6 = -5. 8/6 + 4. 3/6 = -1. 5/6
4) 0,16 - 62/75 = 16/100 - 62/75 = 4/25 - 62/75 = 12/75 - 62/75 = -50/75 = -2/3
5) -1. 5/6 : (-2/3)= -11/6 * (-3/2)= 33/12 = 2. 9/12 = 2. 3/4
