Adding fractions with unlike denominators

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).

What does it mean to have unlike denominators in fractions?

Back

Unlike denominators are denominators that are not the same. To add or subtract fractions with unlike denominators, you must first find a common denominator.

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 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 convert fractions to have a common denominator?

Back

Multiply the numerator and denominator of each fraction by the same number so that both fractions have the common denominator.

Front

What is the process for adding fractions once they have a common denominator?

Back

Add the numerators of the fractions together while keeping the common denominator the same.

Front

What do you do if the sum of the numerators results in a fraction greater than the denominator?

Back

If the sum of the numerators results in a fraction greater than the denominator, simplify the fraction if possible, or convert it to a mixed number.

Front

What is a mixed number?

Back

A mixed number is a whole number combined with a proper fraction, such as 1 and 1/6.

Front

How do you simplify a fraction?

Back

To simplify a fraction, divide both the numerator and the denominator by their greatest common divisor (GCD).

What is the greatest common divisor (GCD)?

Back

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