Today, we will change fractions to terminating and repeating decimals.  To change a fraction to a decimal you divide the numerator by the denominator.

                       .  6

                   _____

ex.  3/5 = 5 | 3 . 0            so 3/5 = 0.6

                   -3   0

                  ______

                          0

The .6 is a terminating decimal because it stops with a remainder of 0.

A repeating decimal is a decimal number that repeats a single digit or group of digits.

                   __

ex.  1/3 =  0.3

When you divide 1 by 3 the 3 repeats.  Once it repeats 3 times you can consider it to be a repeating decimal.  You write the number of group of numbers one time and put a bar on top of the number or group of numbers that repeat.

We will also receive in class a list of 41 fraction to decimal equivalents to divide.

We will also introduce the calculator to help with converting fractions to decimals.
