Week of Sept. 21st

Last week we began discussing mixed number operations.  We reviewed addition and subtraction of mixed numbers along with subtracting mixed numbers where you have to borrow.  We determined that there are six basic steps to add or subtract mixed numbers.

Step 1 - Find a common denominator.
Step 2 - Change your numerator to match (what you did to change the denominator you do the same thing to the numerator).
Step 3 - Add or subtract your numerators (Borrow if you need to).
Step 4 - Keep your new denominator.
Step 5 - Add or Subtract your whole parts
Step 6 - SIMPLIFY!!!!!
