Say there's 2/3 and 1/2, it's called Least Common Denominator, so you need to look at the denominators which are 3 and 2.
Now list the multiples:
3: 1, 3, 6...
2: 1, 2, 4, 6...
As you can see both of them go into 6 the least amount of times because it's the one that they both can multiply.

How do you find the lcd of fractions?
No sure way.just list the factors and circle common ones
Why are equivalent fractions important when adding and subtracting fractions?
Because to add or subtract two fractions you first have to find equivalent fractions for both which have the same denominator.
How would you find the LCD when adding or subtracting rational expressions with different denominators?
No
What is the importance of reducing fractions to lowest term?
In order to find the LCD when adding or subtracting fractions
What is the algorithm for adding fractions?
LCD
Adding dissimilar fractions?
In adding dissimilar fractions first you have to find the LCD! -> LCD means Least Common Denominator. *For example 2/3 3 6 9 12 + 3/4 4 8 12 the LCD is 12 put 12 under the - divide 12 to denominator and write the answer in left of given question
What is an LCD in math?

Do you need to find the LCD in multipliying?
When multiplying fractions, it is not necessary to find the LCD first.
When do you use LCD in math?
When adding or subtracting fractions with different denominators then their LCD must be found in order to carry out the calculations.
What is the meaning of LCD Fraction?
The Lowest Common Denominator is needed when adding or subtracting fractions.
How does the concept of LCM relate to fractions?
When you are adding or subtracting fractions with unlike denominators, you need to find a least common denominator, or LCD. The process is the same as finding an LCM between two integers.
How the LCD of two or more fractions could be of use?
Once you find the LCD, convert the fractions to their equivalents and then you can add and/or subtract them correctly.
How do you write fractions as equivalent fractions with the LCD?
(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.
What is the LCD of 14 over 15?
You need at least two fractions to find an LCD.
What is an application of LCD?
Adding fractions. 1/5 + 1/2 need a common denominator to add.
