What does it mean for fractions to have unlike denominators?

Back

Fractions have unlike denominators when the denominators (the bottom numbers) are different, making it necessary to find a common denominator to compare or operate on them.

Front

How do you compare fractions with unlike denominators?

Back

To compare fractions with unlike denominators, convert them to equivalent fractions with a common denominator, then compare the numerators.

How do you find a common denominator for two fractions?

Back

To find a common denominator, identify the least common multiple (LCM) of the denominators of the fractions.

Front

What is the least common multiple (LCM)?

Back

The least common multiple (LCM) of two or more numbers is the smallest number that is a multiple of each of the numbers.

Front

How can you convert a fraction to an equivalent fraction?

Back

To convert a fraction to an equivalent fraction, multiply or divide both the numerator and the denominator by the same non-zero number.
