Fraction Operations

Fractions represent parts of a whole. Understanding how to perform operations with fractions is important for many mathematical and real-world applications.

Addition and Subtraction

To add or subtract fractions:

  1. Find a common denominator
  2. Convert each fraction to an equivalent fraction with the common denominator
  3. Add or subtract the numerators, keeping the common denominator
  4. Simplify the result if possible
Multiplication

To multiply fractions:

  1. Multiply the numerators together
  2. Multiply the denominators together
  3. Simplify the result if possible
Division

To divide fractions:

  1. Invert the second fraction (flip the numerator and denominator)
  2. Multiply the first fraction by the inverted second fraction
  3. Simplify the result if possible
Simplifying Fractions

To simplify a fraction:

  1. Find the greatest common divisor (GCD) of the numerator and denominator
  2. Divide both the numerator and denominator by the GCD
Fraction Addition/Subtraction Formula:
\( \frac{a}{b} \pm \frac{c}{d} = \frac{ad \pm bc}{bd} \)
Fraction Multiplication Formula:
\( \frac{a}{b} \times \frac{c}{d} = \frac{ac}{bd} \)
Fraction Division Formula:
\( \frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c} = \frac{ad}{bc} \)
