8 razy 4 1/4 - 11 1/5 : 9 1/3 - (- 2 1/3 ) : 5/3
----------------------------------------------------- =
14: 2 2/9 + 8 2/5 razy 1 2/7

8 razy 17/4 - 56/5 : 28/3 - (- 7/3 ) : 53
---------------------------------------------- =
14 : 20/9 + 42/5 razy 9/7

136 /4 - 56/5 razy 3/28 + 7/3 : 5/3
------------------------------------------ =
14 razy 9/20 + 54/5

136/4 - 6/5 + 7/3 razy 3/5
------------------------------- =
126/20 + 54/5

136/4 - 6/5 + 7/5
-------------------- =
63/10 + 108/10

136/4 - 13/5
---------------- =
172/10

680/20 - 52/20
----------------- =
172/10

628/10 : 172/10 = 628/10 razy 10/172 = 3 28/43
