                  one-third

                  When we divide a whole thing into three equal                             1 (one-third)       1

                  parts, each part is called one-third. We write                            3                   3 (one-third)
                                   1
                  one-third as  .
                                   3                                                                            1
                  Here, a pizza is cut into three equal parts. Each                                             3  (one-third)
                                                       1                                1
                  part of the pizza is one-third           of the whole. We read   as 1 upon 3 or 1 by 3.
                                                       3                                3
                  Note that three one-thirds make a whole.

                  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.

                       Shade the part that represents one-third.

                  one-fourth or quArter

                  When we divide a whole thing into four equal parts,
                  then each part is called one-fourth or a quarter.                             1  (one-fourth)  1  (one-fourth)
                                                 1                                              4             4
                  We write one-fourth as  .
                                                 4
                  Here, an apple is cut into four equal
                                                         1
                  parts. Each part is one-fourth             of
                                             1           4
                  the whole. We read   as 1 upon 4

                  or 1 by 4.                 4

                  Note that four one-fourths make a whole.                                      1  (one-fourth)  1  (one-fourth)
                                                                                                4             4
