LCD means lowest (or least) common denominator, and that implies there must be at least two fractions involved for something to be common to both of them. There is, therefore, no sensible answer to this question.
since 9 and 11 have no common factors, the LCD is 99
There is none because the Least Common Denominator (or LCD) refers to the Least Common Multiple (LCM) of the denominators of two or more fractions or mixed numbers. Even if you converted your whole numbers (x) to their fraction equivalents (x/1), the LCD would always be 1.
the answer is 11 over 9
7 + 9 + 11 = 27. Divide by 3. = 9.
The numbers are -12, -11, -10 and -9.
LCD(2, 9, 11) = 198.
99
99
LCD(8, 11, 9) = 792
LCD(11, 16) = 176
since 9 and 11 have no common factors, the LCD is 99
LCD(11, 9, 6) = 198
The lcd of 11 is 11.
LCD(9, 3) = 9
The LCD of 20 and 9 is 180.
LCD(9, 21) = 63
LCD(9, 15) = 45
