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.
To subtract fractions, you need a common denominator. In this case, the common denominator for 10 and 15 is 30. Therefore, nine tenths is equivalent to 27 thirtieths, and eight fifteenths is equivalent to 16 thirtieths. Subtracting 16 from 27 gives you 11 thirtieths. Therefore, nine tenths minus eight fifteenths is equal to 11/30.
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.
Oh, dude, the least common multiple of 2, 4, and 9 is 36. It's like the smallest number that all three of those numbers can go into evenly without any leftovers. So yeah, 36 is the magic number that keeps them all happy.
The sum of (eight and nine tenths) plus (nine and eight tenths) is (eighteen and seven tenths). 8.9 + 9.8 = 18.7
