                                                    Exercise 9.1


          1. Write the time shown by the clock.

              (a)                                  (b)                               (c)
                          11  12  1                        11  12  1                         11  12  1
                        10       2                       10        2                       10       2
                        9         3                      9         3                       9         3
                         8       4                        8        4                       8        4
                          7  6  5                          7  6  5                           7  6  5



          2. Draw the hour and minute hands to show the correct time.

              (a)                                  (b)                               (c)
                          11  12  1                         11  12  1                         11  12  1
                        10       2                        10        2                       10       2
                        9         3    10 : 40            9         3      7 : 30           9         3     1 : 25
                        8        4                         8        4                       8        4
                          7  6  5                            7  6  5                          7  6  5


        Reading Time to the Exact Minute                                                             5 minutes

        As we can see, there are 60 marks on the face of the clock, out of                         12
        which 12 are numbered. The minute hand of a clock moves from                         10 11     1  2
        one number to the next in 5 minutes. The interval between two                       9              3
        numbers is divided into 5 equal parts. Each part is 1 minute.

        The  minute  hand  moves  from  one  small  marking  to  the  next  in               8  7      5  4
        1 minute.                                                                                   6
