Comparing and Ordering Fractions with Unlike Denominators Flashcard

Front

What is a fraction?

Back

A fraction represents a part of a whole and consists of a numerator (top number) and a denominator (bottom number).

Front

What does it mean for fractions to have unlike denominators?

Back

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

Front

What is the least common denominator (LCD)?

Back

The least common denominator is the smallest multiple that two or more denominators share, used to find equivalent fractions.

Front

How do you find the least common denominator of 4 and 5?

Back

The least common denominator of 4 and 5 is 20, as it is the smallest number that both 4 and 5 can divide into evenly.

Front

Which is greater: 3/4 or 2/5?

Back

3/4 is greater than 2/5.

Front

Which is smaller: 1/2 or 3/5?

Back

1/2 is smaller than 3/5.

Front

How do you arrange fractions in descending order?

Back

To arrange fractions in descending order, convert them to equivalent fractions with a common denominator and then order them from largest to smallest.

Front

Arrange the following fractions in descending order: 4/9, 2/7, 5/12.

Back

5/12, 4/9, 2/7.

Front

What is an equivalent fraction?

Back

An equivalent fraction is a fraction that represents the same value as another fraction, even though the numerator and denominator are different.
