Common Denominators

A common multiple of the denominators of a set fractions

A common denominator for 1 over 4 and 1 over 6 is 12 because a common multiple of 4 and 6 is 12



Multiples ( skip count )



The product of a given number and a natural number like 1,2,3 and so on



For example some multiples of 3 are 3,6,9,12



1x3=3 ,2x3=6, 3x3=9,3x4=12



List 5 multiples of 4



Don't find factors



4,8,12,16,20,24



1 over 2 and 2 over 3 find common denominator

(find multiples first than find LCF )



multiples of 2 are 2,4,6,8,10 multiples of 3 are 3,6,9,12,15



The LCF is 6 so



1 x3 3

2 x3 6 What you do to the bottom you must do to the top



2 x2 4

3 x2 6 What you do to the bottom you must do to the top


Sorry guys I could add a picture or a video
