If two fractions have unlike denominators then is the Lcd the product of their denominators?

Not necessarily. The product of their denominators is a common denominator, but might not be the smallest. For instance, the LCD of one tenth and one twentieth is 20.

If two fraction have unlike denominators then is the Lcd the product of their denominators?
I was told the Lcd is 4 not 8 is that true
Explain how comparing fractions with like denominators differs from comparing fractions with unlike denominators?
Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).
IS THE LCD OF TWO FRACTIONS THE SAME AS THE LCM NUMERATORS AND FRACTIONS?
The LCD of two fractions is the same as the LCM of their denominators.
What is the LCD for fractions?
The LCD for fractions is the LCM (least common multiple) of all of the denominators.
What I there is isn't a lowest common denominator for a fraction?
There is always an LCD for a set of fractions, even if it's only the product of the denominators.
What is the blank is the least common multiple of the denominators of the fractions?
It is the LCD.
How do you find the LCM multiple for two fractions?
The LCM is used for integers, not fractions. If you're trying to add unlike fractions, take the LCM of the denominators (known in this case as the least common denominator, or LCD), convert the fractions and proceed.
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.
What is the least common denominator for fractions with the denominators 85 110 and 260?
The LCD for these fractions is 48,620.
What is the LCD of 11 and 18?
The LCM of these numbers is 198. (LCD is just the LCM of the denominators of fractions.)
Why would you want to rename fractions with the LCD?
Possible reasons: To add or subtract fractions, To compare fractions with different denominators.
What is three eighths plus one fourth?
The denominators are different, so find the equivalent fractions using the LCD , then add the fractions with the denominators.
