Objective: To Express Rational Numbers as Decimals or Fractions.

 ex(1) as a decimal  ex (2) as a decimal  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 = Look out for ones written incorrectly ex..414

 Case 3: Non-terminating eventually repeating.  ex.432 How many in the repeating block? Two place…two 10’s  100N =  N =.432  99N = 42.8 Wrap it up!
