Пошаговое объяснение:

1) 13ц.3/4 + 9ц.1/6 = 13ц.9/12 + 9ц.2/12 = 22ц.11/12

2) 22ц.11/12 * 1ц.1/5 =275/12 * 6/5 = 55/2

3) 10ц.3/10 - 8ц.1/2 = 10ц.3/10 - 8ц.5/10 = 1ц.8/10 = 1ц.4/5

4) 1ц.4/5 * 5/9 = 9/5 * 5/9 = 1

5) 55/2 : 1 = 55/2

6) 6ц.4/5 - 3ц.2/5 = 3ц.2/5

7) 3ц.2/5 * 5ц.5/6 = 17/5 * 35/6 = 119/6

8) 3ц.2/3 - 3ц.1/6 = 3ц.4/6 - 3ц.1/6 = 3/6 = 1/2

9) 119/6 : 1/2 = 119/6 * 2/1 = 119/3

10) 55/2 + 119/3 = 165/6 + 238/6 = 403/6

11) 403/6 - 27ц.1/6 = 403/6 - 163/6 = 240/6 = 40
