Learng Target

the learning target is "comparing and ordering fractions."

Example

9/10   5/7

10          7

2 5 7

70 least comon denominator(LCD)

63/70 is bigger than 50/70

Lesson

to compare fractions you must do a primefactorazation tree to find the least comon multiple. Take that least comon multiple and use it as your denominator.  Whatever number you multiplied to the denominator you also multiply by the numerator.  You can than tell which number is larger
