5 5/6 + 3 3/4 = 5 10/12 +3 9/12 = 8 19/12 = 9 7/12
5 7/9 -2 1/6 = 5 14/18 - 2 3/18 = 3 11/18    2 16 + 1 89      2 318 + 1 1618 ;     2 16   +   1 89   =   2 318   +   1 1618   = 2 + 1 +   318   + 1618   =

=   3 1918   = 3     2 16   –   1 89   =   2 318   –   1 1618   =   1 2118   –   1 1618+   1 118   =   4 118 .    2 16   –   1 89   =   2 318   –   1 1618   =   1 2118   –   1 1618   =

= 1 – 1 +   2118   –   1618   =   518   .
