                  Example 5: Two containers contain 18 L 300 mL and 17 L 900 mL oil. Find the total quantity

                  of oil in the two containers.
                  Solution:                                                          L         mL

                                                                                   1  1
                         Quantity of oil in the first container             =      1 8      3 0 0            Olive  Sunflower
                                                                                                              Oil
                                                                                                                      Oil
                         Quantity of oil in the second container            =  + 1 7        9 0 0
                         Total quantity of oil in both the containers       =      3 6      2 0 0

                         Thus, the total quantity of oil in both the containers is  36 L 200 mL.

                  Example 6: A milkman sold 80 L 300 mL milk in the morning and 98 L 500 mL in the

                  evening. How much more milk did he sell in the evening than in the morning?

                  Solution:
                                                                             L          mL
                         Quantity of milk sold in the evening        =     9 8       5 0 0
                         Quantity of milk sold in the morning        =  – 8 0        3 0 0

                         Difference in both quantities               =     1 8       2 0 0

                         Thus, in the evening, he sold 18 L 200 mL more milk.
