3 1/2- 1 1/3•1 5/7 +4,5
1 3/5 :16 -4/9•1 1/8

2 2/5:0,4•3 1/6+2 5/6

(1/2)3 + (1 1/4)2- √3 1/6

5,5 : 1,1+ 1,3 / 3•1 2/5

Answer 1

3 1/2 - 1 1/3 * 1 5/7 + 4,5 =                          (4,5 = 4 5/10 = 4 1/2)
3 1/2 - 4/3 * 12/7 + 4 1/2 = 
3 1/2 - 4/1 * 4/7 + 4 1/2 =
3 1/2 - 16/7 + 4 1/2 =
8 - 2 2./7 = 
7 7/7 - 2 2/7 = 5 5/7

1 3/5 : 16 - 4/9 * 1 1/8 =
8/5 * 1/16 - 4/9 * 9/8 =
1/5 * 1/2 - 1/1 * 1/2 =
1/10 - 1/2 =
1/10 - 5/10 =
-4/10 = -2/5

2 2/5 : 0,4 * 3 1/6 + 2 5/6 =
12/5 : 4/10 * 19/6 + 2 5/6 =
12/5 * 10/4 * 19/6 + 2 5/6 =
2/1 * 2/4 * 19/1 + 2 5/6 =
4/4 * 19 + 2/56 =
1 * 19 + 2 5/6 =
19 + 2 5/6 = 21 5/6 

5,5 : 1,1 + 1,3   
-------------------   =
    3 * 1 2/5 


5 + 1,3
------------  =
3 * 7/5


6,3
-------- =  63/10 : 21/5 = 63/10 * 5/21 =  3/2 * 1/1 = 3/2 = 1 1/2 
21/5
