            Observe the following clocks to see the time.



















            Minute hand is at 12                   Minute hand is at 12                    Minute hand is at 12
              Hour hand is at 3                       Hour hand is at 4                      Hour hand is at 6

              Time = 3 O’ clock                      Time = 4 O’ clock                       Time = 6 O’ clock

            Telling the Time Half Hour


            In this clock, the hour hand is between 7 and 8 and the
            minute hand points to 6. The shaded part shows that the

            long hand or minute hand has moved half way round.

                                                            1
            When  the  minute  hand  moves  —  way  round  on  the
                                                            2
            face of the clock, half an hour has passed and we say


            that it is half past seven.

            \ Half past seven can also be written as 7 : 30.


            Also,                                  60 minutes = 1 hour,

                                          30 minutes = One-half of an hour
















                     11 : 30                                  6 : 30                              10 : 30

              30 minutes to 12                            (half past 6)                       (half past 10)

                    30 to 12                                 30 to 7                             30 to 11
