The common denominator of 3 & 9 is 9,as because-3*1=33*2=63*3= 9&.....9*1= 9So here the 9 matches first.
You need at least two numbers to find a common denominator.
the least common denominator is very simple. just take 9/18 for example reduce it. 9 goes in to 18 2 times and nine goes in nine once sooo 9/18 = 1/2 that means two is the the least common denominator.
