Пошаговое объяснение:
1) 5. 4/13 * 7. 1/6 = 69/13 * 43/6 = 2967/78 = 38. 3/78
2) 3/20 - 2/5 - 1/4 =
3/20 - 8/20 - 5/20 = -10/20 = -1/2
3) 20 * (-1/2) = -20/2 = -10
4) 6. 9/13 * 7. 1/6 = 87/13 * 43/6 = 3741/78 = 47. 75/78
5) 38. 3/78 - (-10) =
38. 3/78 + 10 = 48. 3/78
6) 48. 3/78 + 47. 75/78 =
95. 78/78 = 96
