Пошаговое объяснение:
1) -13,5 : 1,5 = -9
2) 6. 1/2 * 1. 5/11 =
13/2 * 16/11 = 13/1 * 8/11 = 104/11 = 9. 5/11
3) -9 - 9. 5/11 = -18. 5/11
4) -19,25 * 4/22 = -19. 25/100 * 4/22 =
-19. 1/4 * 4/22 = -77/4 * 4/22 = -77/22 = -7/2 = -3. 1/2
5) -18. 5/11 + (-3. 1/2) = -18. 5/11 - 3. 1/2 = -18. 10/22 - 3. 11/22 = -21. 21/22
