Answer 1

1.  6 13/22 + 5 5/11 : ( - 4 ) - 5/132 : ( - 1/6 ) + ( - 5/6 ) : 1 7/18 = 4.4.

                               Решение по действиям:

1)  5 5/11 : ( - 4 ) = 60/11 : ( - 4/1 ) = 60/11 * ( - 1/4 ) = - 60/44 = - 15/11 =

    = - 1 4/11.

2) 6 13/22 + ( - 1 4/11 ) = 6 13/22 - 1 8/22 = 5 5/22.

3)  5/132 : ( - 1/6 ) = 5/132 * ( - 6/1 ) = - 30/132 = - 5/22.

4)  5 5/22 - 5/22 = 5.

5)  ( - 5/6 ) : 1 7/18 = - 5/6 : 25/18 = - 5/6 * 18/25 = - 1/6 * 18/5 =

    = - 18/30 = - 6/10 = - 3/5.

6)  5 + ( - 3/5 ) = 5 - 3/5 = 4 5/5 - 3/5 = 4 2/5 = 4,4.
