Adding and Subtracting Fractions Practice

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 is the least common denominator (LCD)?

Back

The least common denominator is the smallest number that can be a common multiple of the denominators of two or more fractions.

Front

How do you find the least common denominator of \(\frac{6}{8}\) and \(\frac{4}{12}\)?

Back

The least common denominator of \(\frac{6}{8}\) and \(\frac{4}{12}\) is 24.

Front

What is the process to add fractions with different denominators?

Back

To add fractions with different denominators, first find the least common denominator, convert each fraction to an equivalent fraction with the LCD, and then add the numerators.

Front

What is \(2 \frac{2}{10} + 5 \frac{1}{5}\)?

Back

The sum is \(7 \frac{2}{5}\).

Front

How do you simplify a mixed number?

Back

To simplify a mixed number, convert it to an improper fraction and then simplify if possible.

Front

What is \(\frac{1}{8} + \frac{5}{8}\)?

Back

The sum is \(\frac{6}{8}\) or \(\frac{3}{4}\).

Front

How do you subtract fractions?

Back

To subtract fractions, ensure they have the same denominator, then subtract the numerators and keep the denominator the same.

Front

What is \(\frac{5}{6} - \frac{1}{3}\)?

Back

The result is \(\frac{1}{2}\).

Front

What is the result of \(\frac{4}{15} - \frac{2}{15}\)?

Back

The result is \(\frac{2}{15}\).
