9 is.
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.
the common denominator for 9/8 and 7/20 is 40. (45/40 and 14/40)
9/10
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions. Even if you converted your numbers (x) to their fraction equivalents (x/1), the LCD will always be 1.
common denominator of eight and nine
