                example 3. The total weight of three friends, Panda, Koala and Penguin, is 58 kg. Penguin’s
                weight is 27 kg 250 g and Koala’s weight is 8 kg 550 g. What is Panda’s weight?
                Solution. Total weight of the three friends = 58 kg

                                              Penguin’s weight = 27 kg 250 g

                                                Koala’s weight = 8 kg 550 g

                          Penguin and Koala’s total weight = 27 kg 250 g + 8 kg 550 g

                                                                   = 35 kg 800 g

                                           So, Panda’s weight = 58 kg – 35 kg 800 g

                                                                   = 22 kg 200 g

                Thus, Panda’s weight is 22 kg 200 g.
                example  4.  A leopard and a wolf were weighed on a scale. The leopard weighed

                60725 g. The wolf weighed 36 kg 375 g less than the leopard. Find the weight of the
                wolf.

                Solution. Leopard’s weight = 60725 g = 60000 g + 725 g

                                                              = (60000 ÷ 1000) kg + 725 g

                                                              = 60 kg 725 g

                Difference in the weights of the leopard and the wolf = 36 kg 375 g

                                            Wolf’s weight  = 60 kg 725 g – 36 kg 375 g

                                                              = 24 kg 350 g

                Thus, the wolf’s weight is 24 kg 350 g.

                            Exercise 9F

                    1.  Find the sum.
                        a.        kg      g            b.         kg      g            c.        kg      g

                                 300 000                         243    550                     500 540
                               + 287     204                   + 178    004                   + 239     261

                    2.  Write in the vertical form and add the following:

                        a.  48 kg 948 g and 13 kg 666 g                     b.  26 kg 430 g and 27 kg 570 g
                        c.  45 kg 585 g and 48 kg 894 g                     d.  360 g 870 mg and 140 g 550 mg
