9.5 Subtract Mixed Numbers (p.214-217)

I.Subtract mixed numbers that require borrowing from the whole:
-Use the same steps as before but borrow from a whole when subtracting a larger fraction or turn into improper fractions and then simplify.

Ex. 4 1/2 - 2 4/5 :
-- find a common denominator
4 1/2 = 4 5/10
- 2 4/5 = 2 8/10
--The fraction 8/10 is larger than 5/10 so you need to borrow from the 4 whole.
4 5/10 = 3 15/10 (as an improper fraction)
--Use the improper fraction when subtracting
3 15/10
-2 8/10
-----------
0 7/10 = 7/10
