Want this question answered?
The LCD of two fractions is the same as the LCM of their denominators.
When the denominators are relatively prime, that is, they have a GCF of 1.
LCD is the Lowest Common Denominator which is the lowest number into which the denominators of all the fractions will each divide exactly. Each of the fractions can then be converted to an equivalent fraction with the new denominator which then allows the fractions to be added and/or subtracted.
There are an unlimited number of common denominators if you want to use ridiculously large numbers. There is ONLY ONE Least Common Denominator (LCD, LCM).
The least common multiple of two or more denominators is known as the least common denominator, or LCD.
The LCD of two fractions is the same as the LCM 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.
I was told the Lcd is 4 not 8 is that true

The two numbers are relatively prime, since 11 is a prime number and it doesn't evenly divide 24, so the LCM (the LCD of two fractions is the LCM of their denominators) is just their product: 264.

Only if you have just two fractions.
The Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions. I assume the 7 and 21 are the denominators of two fractions you need to add or subtract.LCD(7, 21) = 21.
LCD is the Lowest Common Denominator which is the lowest number into which the denominators of all the fractions will each divide exactly. Each of the fractions can then be converted to an equivalent fraction with the new denominator which then allows the fractions to be added and/or subtracted.
You multiply the two fractions. To multiply two fractions, the numerator of the result is the product of the numerators, and the denominator of the result is the product of the denominators.
