      Adding Fractions with different 
               denominators
   Problem: 
   You can’t add fractions with different denominators without getting them 
   ready first. They will be ready to add when they have common 
   denominators
   Solution: 
   Turn  fractions into equivalent fractions with a common 
   denominator that is find the Lowest Common Multiple (LCM) of 
   the two denominators
               Finding the 
     Lowest Common Denominator 
    • The lowest common multiple of two numbers is 
      the lowest number in BOTH lists of multiples
    1  1           Multiples of 2 are 2, 4, 6, 8, 10……
                 Multiples of 3 are 3, 6, 9, 12, ………
    2  3
                   What is the lowest common multiple?
                     Finding the 
       Lowest Common Denominator 
      • The lowest common multiple of two numbers is 
        the lowest number they will BOTH divide into
     1    1                  2 divides into 2, 4, 6, 8…..
                             3 divides into 3, 6, 9….
     2    3
                       What is the lowest number 2 and 3  both divide into?
