              Addition and Subtraction of Weight


            Example  :  Add 75 kg 582 g and 13 kg 410 g.                                              kg        g

                                                                                                     7 5    5 8 2
            Solution  :  Step 1        :  Add the grams’ column.
                                                                                                 +  1 3    4 1 0
                          Step 2 :  Add the kilograms’ column.
                                                                                                     8 8    9 9 2
                                  \ 75 kg 582 g + 13 kg 410 g = 88 kg 992 g


            Example  :  Subtract 28 kg 340 g from 48 kg 220 g
                                                                                                      kg        g

            Solution  :  Step 1 :  Subtract the grams’ column.                                       4 8    2 2 0

                          Step 2 :  Subtract the kilograms’ column.                               –  2 8    3 4 0

                                                                                                     1 9    8 8 0
                                  \ 48 kg 220 g – 28 kg 340 g = 19 kg 880 g

            1.  Use different ways to make a kilogram.

                 a.  Using only 100 g = ______          = 1 kg

                 b.   Using only 200 g = ______        = 1 kg

                 c.  Using only 500 g = ______          = 1 kg

                 d.  Using only 200 g and 50 g = ______            = 1 kg
            2.  Balance the scales by writing the extra weights needed.

                 a.  500 g + 200 g + ______        g + ______   g = 1000 g

                 b.  800 g + ______      g + ______   g = 1000 g

                 c.  700 g + ______      g + ______   g = 1000 g

                 d.  200 g + ______      g + ______   g + ______   g = 1000 g

            3.  Solve the following.

                 a.  5 kg 64 g + 3 kg 95 g = ______         kg ______  g
                 b.  3 kg 60 g + 8 kg 70 g = ______         kg ______  g

                 c.  5 kg 7 g – 4 kg 4 g = ______       kg ______  g

                 d.  5 kg 6 g – 3 kg 9 g = ______       kg ______  g
