If that's 3/11 and 2/5, the LCD is 55.
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==========
If that's 84 and 35, the LCD is 420.If that's 8/4 and 3/5, the LCD is 20.
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.
You need at least two fractions to find something in common.
The LCD for 5/9 and 4/5 is 45.

5/8 is one fraction. You need at least two fractions to find something in common.

To do additions with mixed fractions, you should add the integer (whole) part, and the fractions, separately.
If that's 3/11 and 2/5, the LCD is 55.
If you are using the word "over" to describe that these numbers are fractions, then 1/9 plus 4/9 is 5/9. Since the denominators are the same, you simply add the numerators of both fractions, and you have your answer, 5 over 9.
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
