3.  Shade 8 horizontal strips to represent 0.8 (8 parts out                                     0.8
                            8
                  of 10 =      = 0.8).
                           10













              4.  Further divide the square into 10 equal parts by drawing                                    0.8
                  vertical lines.









                                                                                      0.2
              5.  Shade 2 vertical strips by a different colour to represent
                  0.2.
              6.  The double shaded small squares represent the product.

                   Number of double shaded small squares = 16                                                 0.8
                   Total number of small squares = 100

                   Double shaded squares represent       16   = 0.16
                                                        100

                   So, 0.8 × 0.2 = 0.16









                   Now, find 0.5 × 0.9 by shading the adjoining square.
