Adding 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 to add fractions with unlike denominators?

Back

It means to add fractions that have different denominators, requiring a common denominator to be found first.

Front

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.

Front

What is the least common multiple (LCM)?

Back

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

Front

What is the first step in adding fractions with unlike denominators?

Back

The first step is to find a common denominator for the fractions.

Front

How do you simplify a fraction?

Back

To simplify a fraction, divide the numerator and the denominator by their greatest common factor (GCF).

Front

What is the greatest common factor (GCF)?

Back

The greatest common factor is the largest number that divides both the numerator and the denominator without leaving a remainder.
