                  3.  Decide which containers have a capacity of less than 1 L.
                        (a)                      (b)                     (c)                      (d)

                  4.  Write the quantity of liquid as shown in the beakers.

                        (a)                      (b)                     (c)                      (d)
                                         mL                       mL                       mL                       mL

                  ADDITION AND SUBTRACTION OF CAPACITIeS

                  Addition of Capacities

                  To add the capacities of two or more containers in litres or millilitres, we simply

                  add the numbers and write down the unit.

                  Example 1: Add the following.

                                 (a) 63 L + 68 L               (b) 486 L + 158 L            (c) 178 mL + 556 mL

                  Solution:  (a)          1 1                  (b)     1 1                  (c)     1 1

                                              6 3 L                    4 8 6 L                      1 7 8 mL

                                      +       6 8 L                 +  1 5 8 L                   +  5 5 6 mL
                                          1 3 1 L                      6 4 4 L                      7 3 4 mL
                  Subtraction of Capacities

                  To subtract the capacities of two containers, we simply subtract the smaller number

                  from the bigger number and write down the unit.

                  Example 2: Subtract the following.

                                 (a) 90 L – 55 L                             (b) 732 mL – 367 mL

                  Solution:  (a)          8 10                               (b)      6 12 12
                                          9 0 L                                       7 3 2 mL

                                      –   5 5 L                                    –  3 6 7 mL
                                          3 5 L                                       3 6 5 mL
