Пошаговое объяснение:
1) 8. 1/6 - 5/18 = 8. 3/18 - 5/18 = 7. 21/18 - 5/18 =
7. 16/18 = 7. 8/9
2) 7. 8/9 : 14/27 = 71/9 : 14/27 = 71/9 * 27/14 = 71/1 * 3/14 = 213/14 = 15. 3/14
3) 10. 7/8 : 3/4 = 87/8 : 3/4 = 87/8 * 4/3 = 29/2 * 1/1 = 29/2
4) 29/2 * 2/3 = 29/3 = 9. 2/3
5) 5. 3/7 : 6. 1/3 = 38/7 : 19/3 = 38/7 * 3/19 = 2/7 * 3/1 = 6/7
6) 9. 2/3 + 6/7 = 9. 14/21 + 18/21 = 9. 32/21 = 10. 11/21
7) 10. 11/21 * 3/17 =
221/21 * 3/17 = 13/7 * 1/1 = 13/7 = 1. 6/7
8) 15. 3/14 - 1. 6/7 =
15. 3/14 - 1 . 12/14 =
14. 17/14 - 1. 12/14 = 13. 5/14
