1.1 Rational Numbers

Objective: To Express Rational Numbers as Decimals or Fractions.

ex(1) as a decimal 8 5.000

ex (2) as a decimal 11 5.00000

Note: Every rational number can be written as either a terminating decimal or a decimal that eventually repeats. (A fraction repeats in a block

fewer than d digits.

Terminating“has an end”

Non-Terminating“repeating”

Case 1: Terminating .025 = =

Case 2: Non-terminating Strictly Repeating.

ex(1) .3 = =

ex(2) .77 =

To express a decimal as a fraction…

Look out for ones written incorrectlyex. .414

Case 3: Non-terminating eventually repeating.

ex .432 How many in the repeating block? Two place…two
