1/6 is one fraction. You need at least two fractions to find something in common.
1/3 and 3/8 have a lcd of 24 (8/24 and 9/24)
28 in this case.
If that's 84 and 35, the LCD is 420.If that's 8/4 and 3/5, the LCD is 20.
Assuming you mean the LCM (Least Common Denominator of 2 fractions is the LCM of the denominators, which for 7/1 and 16/1 is 1), the answer is 112.
The LCD, or Lowest Common Denominator, is the smallest multiple of each of the denominators of a set of fractions. So, assuming that 2, 4 and 5 are denominators of fractions (1/2, 1/4 and 1/5, for example), the LCD would be 20, because 20 is the lowest number that 2, 4 and 5 multiply into. So, your new fractions would be 10/20, 5/20 and 4/20. The purpose of finding the LCD is to allow for multiplying fractions together, or simply comparing them easily.

The LCD for working with those fractions is 8 (or 1/8)
1/3 and 1/4
(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)
28 in this case.
The LCD for these two fractions is 6.
Adding fractions. 1/5 + 1/2 need a common denominator to add.
Not true. Try 1/6 + 1/3
