                  When we divide a whole thing into

                  three equal parts, each part is called

                  parts. Each part of pizza is one-third           of the whole. We read   as 1 upon 3 or 1 by 3.

                  1.  tick () the shapes that are divided into equal parts.

                       (a)                (b)                  (c)                  (d)                 (e)

                  2.  Colour one-half of each figure.

                       (a)                 (b)                 (c)                 (d)                (e)

                  3.  Colour one-third of each figure.

                       (a)                 (b)                 (c)                 (d)                (e)

                  4.  Draw a square and divide it into three equal parts. Mention which part represents
                       one-third.

                  one-fourth or quarter                                                         1             1

                  When we divide a whole thing into
                  four equal parts, then each part is
                  called one-fourth or a quarter. We
                                            1
                  write one-fourth as  .

                  Here, an apple is cut into four equal
                                                         1
                  parts. Each part is one-fourth             of                                 1  (one-fourth)  1  (one-fourth)
                                             1           4                                      4             4
                  the whole. We read   as 1 upon 4 or 1 by 4.
                                             4

                  Note that four one-fourths make a whole.
