                                                                                                            4
                Number of pieces in a chocolate bar = 4 × 2 = 8
                We also know that 8 ÷ 2 = 4 and 8 ÷ 4 = 2

                Thus, most multiplication facts have two corresponding                      2
                division facts.
                   Multiplication fact                      Division fact                          Think!

                                                              72 ÷ 9 = 8                      How many division
                         8 × 9 = 72                                                           facts are there for
                                                              72 ÷ 8 = 9                      5 × 5 = 25?

                It is clear that division is the inverse of multiplication.

                            Exercise 5C

                    1.  Look at the number lines given below and fill in the boxes.

                        a.

                        b.

                        c.

                    2.  Using a number line, divide the following:
                        a.   16 ÷ 2 = ___        b.   24 ÷ 12 = ___       c.   36 ÷ 6 = ___        d.    15 ÷ 3 = ___

                    3.  Write two division facts for the following multiplication facts:
                        a.   4 × 8 = 32                  b.    9 × 6 = 54                  c.   7 × 8 = 56
                             ___ ÷ ___ = ___                   ___ ÷ ___ = ___                  ___ ÷ ___ = ___
                             ___ ÷ ___ = ___                   ___ ÷ ___ = ___                  ___ ÷ ___ = ___

                    4.  Write the multiplication facts for the following division facts:
                        a.   40 ÷ 5 = 8                  b.    44 ÷ 11 = 4                 c.   48 ÷ 8 = 6
                             ___ × ___ = ___                   ___ × ___ = ___                  ___ × ___ = ___
