LCD(12, 20) = 60
To find the least common denominator (LCD) of one quarter (1/4) and three tenths (3/10), first determine the denominators, which are 4 and 10. The multiples of 4 are 4, 8, 12, 16, 20, and the multiples of 10 are 10, 20, 30. The smallest common multiple of both numbers is 20, so the LCD is 20.
If that's 5/12, 10/13 and 7/9, the LCD is 468.
2/12=1/6 The LCD of 1/6 and 3/4=The LCD of 1/6 and 1/4=12 Therefore, 2/12 and 9/12 have the same denominator. They are equal to the original fractions. LCD=12
