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.
LCD(4, 2, 9) = 36
36
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
LCD(9, 3y) = 9y
it is 1

LCD(9, 3) = 9
Obtain the LCD (lowest common denominator). Is 2/3 larger than 3/4? (2*4)/(3*4)=8/12 (3*3)/(4*3)=9/12 No.
36
If that's 9/10 and 2/3, the LCD is 30.
2/3 and 3/4Looks like 12 here, so use form of one to convert both fractions to LCD form.4*2/4*3 and 3*3/3*48/12 and 9/12==========
