LCD(4, 2, 9) = 36
LCD(9, 3y) = 9y
36
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 is y E
36
LCD(7, 9, 2) = 126.
LCD(2, 9, 11) = 198.
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
36
LCD(3, 5, 4, 2) = 60
the answer is 180
