                         Changing a Fraction to an Equivalent Decimal Fraction. Recall that a fraction is
                      made up of a numerator and denominator and a line between identifies the arithmetic
                      function of division,
                                                           numerator
                                                         denominator

                      and can be written as numerator ÷ denominator.
                         Thus the fraction 3/4 may be interpreted to mean division and may be rewritten as 3 ÷ 4.
                      Even though it is not shown, the decimal point is understood to fall just to the right of a
                      whole number. When performing the arithmetic indicated the resulting answer is (3 ÷ 4 =)
                      0.75.

                         With pencil and paper you would write:

                                     .75
                         ¾  = 4 )3.00

                         Perform this calculation with your hand calculator in this order:

                                1.  Tap the clear key.             Cl/C
                                2.  Tap the 3 key.                  3

                                3.  Tap the divide key (÷).
                                                                    ÷
                                4.  Tap the 4 key.                  4

                                5.  Tap the = sign key.             =

                                6.  Answer 0.75 appears on your screen.
