it is 1
LCD(9, 3) = 9
If that's 9/10 and 2/3, the LCD is 30.
To find the least common denominator (LCD) of the fractions with denominators 3, 4, 2, and 9, we need to determine the least common multiple (LCM) of these numbers. The prime factorization of each number is: 3 (3), 4 (2^2), 2 (2), and 9 (3^2). The LCM takes the highest power of each prime: 2^2 and 3^2, resulting in 4 × 9 = 36. Therefore, the LCD of 3, 4, 2, and 9 is 36.
the LCD of 2, 9 and 5 = 90
LCD(4, 2, 9) = 36
LCD(7, 9, 2) = 126.
LCD(2, 9, 11) = 198.
The smallest multiple 3 and 9 have in common is 9. 2/3 becomes 6/9 and 5/9 does not change
36
9 multiplied by 14 is 126. So believe it or not the LCD of 2/9 and 3/14 is 126.
lcd(22, 12, 16, 9) = 1584 22 = 2 x 11 12 = 2^2 x 3 16 = 2^4 9 = 3^2 lcd = 2^4 x 3^2 x 11 = 1584
