          Note how we say dimensions:     3.520  = three  point  five  two  oh
                                          0.370  =  (nought/zero/oh)  point  three  seven  oh
                                          (We do NOT say three  point  fifty-two,  or  three  point  five  hundred
                                          and  twenty.)
          1  inch  = approximately 25 millimetres   This  board  is  30  x  600.  =  This  board  is  30  by  600.

                          7  Write these  dimensions  in words.

                             on  this  page. Student  B look  at the information on page 70.
















                              A:  What  are  the  dimensions  of  the  rod?
                              B:  It's  4.35  metres  long,  ....
                             A:  What  about  the  radius?
                              B:  The  radius  is  ...  .
