                example 6.  A bottle contains          5   litres of milk. If   3   litres were taken out, how much
                                                       8                      8
                milk was left in the bottle?
                                                                  5
                Solution. Quantity of milk in the bottle =   L
                                                    3             8
                Quantity of milk taken out =   L
                                                    8
                                                            5
                Quantity of milk left in the bottle =            3     5    3  =   2  =  1   L
                        1                                   8    8       8      8     4
                Thus,   L of milk was left in the bottle.
