Learning Target:
Comparing and ordering fractions.
Example:
3/12 2/8 Change denominator!
12 8
/\ /\ 3/12 2/8
3*4 2*4 -SO- /\ /\ -SO- 3/12 = 2/8
/\ /\ 6/24 6/24
2*2 2*2
3*2*2*2=24 24=least comman denominator (LCD)
Notice:
Same denominator (numorator is the same by conicidence) We use this to simplify and make it easier to find (LCD).
Use:
<,>,=,
Steps:
1. Find the least common multiple of the denominator to get the Least Common Denominator (LCD).
2. Rewrite each fraction as an equivalent fraction using LCD.
