LCD = LCD(a, 2b, 3c) = 6abc
If that's 1/8, 2/9, 1/4, the LCD is 72

1/3 and 3/8 have a lcd of 24 (8/24 and 9/24)
6abc
6x
LCD = LCD(a, 2b, 3c) = 6abc
The LCD for working with those fractions is 8 (or 1/8)
1/3 and 1/4
If that's 1/8, 2/9, 1/4, the LCD is 72
(1) find the LCD. (2) find the factor that each original denominator needs to be multiplied by to get the LCD. (3) multiply both the numerator and the denominator by that factor.

Find lcd for both fractions = 300, so (4/300) / (75/300), divide numerators = 4/75
Find the LCD, in this case 4 and then add the fractions, so the problem can now be written as:2/4 + 1/4 = 3/4
1/4 + 1/5 = 9/20 Answer: To add fractions with different denominators, get the Least Common Denominator (LCD) of the addends first, then add the numerators of the fractions. In 1/4 + 1/5, the LCD is 20. 1/4 = 5/20 1/5 = 4/20 .......===== ....... 9/20
1/3 and 3/8 have a lcd of 24 (8/24 and 9/24)
