Answer: I assume you are talking about the least common denominator.

If you multiply the denominators, you will get a common denominator. This will always work, if you need to add, subtract, or compare fractions.

However, the common denominator you thus get will not always be the LEAST common denominator. Examples:

* For denominators 7 and 11, the least common denominator is, indeed, the product (77).

* For denominators 4 and 6, the product is 24, but the least common denominator is 12.

* The difference can be more extreme, too; for denominators 100 and 200, the product is 20,000, but the least common denominator is only 200.

* Or even more extreme: if both fractions have the denominator 551, the product is 303,601. The least common denominator, of course, is just 551.

I was told the Lcd is 4 not 8 is that true

unlike denominators: the bottom number of a fraction. to have unlike denominators you must have two fractions with a different number on the bottom of each fraction.

Unlike or dissimilar fraction.

The definition is a different denominator in a fraction

because they are the same number

i give up i have been asking this question for 9 years a unlike fraction is where you have two or more fractions and the denominators are all different

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.

Like fractions have the same denominators (bottom part of fraction), unlike fractions do not.

The denominator is the bottom number in a fraction. Fractions like 1/3 and 1/4 have different numbers on the bottom. Those are unlike denominators.

fractions having same denominators are like fractions & others are unlike fractions

You need to answer this question because your teacher is looking for your critical thinking skills and how well you understood the lesson.

Multiply all numerators to get numerator of the product. Multiply all denominators to get denominator of the product. This is true whether the factors have like or unlike denominators.
