Objective: compare fractions by using the least common denominator

What you should understand:

­you can compare two fractions that have different denominators by rewriting equivalent fractions using the least common denominator

Example:  Compare   2         1  

Least common denominator of 3 & 5 = 15

  2       5   10   1    3     3 3       5    15              5    3    15

3         5

Step 1Find a common denominator by finding the Least Common Multiple (LCM)

35

23

The common denominator is ____________

Multiples of 5: 5, 10, 15, 20, 25, 30...

Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30...

Circle the common multiples. Put a square around the LCM.

I can compare fractions with different denominators
