Пошаговое объяснение:
( 10 - 5 2/3 - 8,5) : ( -4 2/9 + 5 5/18)= - 3 18/19
1) 10 - 5 2/3 = 9 3/3 - 5 2/3 = 4 1/3
2) 4 1/3 - 8 1/2 = 13/3 - 17/2 = 26/6 - 51/6 = - 25/6
3) -4 2/9 + 5 5/18 = - 4 4/18 + 5 5/18 = 1 1/18
4) (- 25/6) : 1 1/18 = -25/6 * 18/19 = - 3 18/19
1) 10 - 5. 2/3 = 9. 3/3 - 5. 2/3 = 4. 1/3
2) 4. 1/3 - 8,5 = 4. 1/3 - 8. 5/10 = 4. 10/30 - 8. 15/30 = -4. 5/30 = -4. 1/6
3) -4. 2/9 + 5. 5/18 = -4. 4/18 + 5. 5/18 = 1. 1/18
4) -4. 1/6 : 1. 1/18 = -25/6 : 19/18 = -25/6 * 18/19 = -25/1 * 3/19 = -75/19 =
-3. 18/19
