Basic Fraction Multiplication: To multiply two fractions, multiply their numerators and denominators. Simplify the result if possible.

Cross-Cancelling for Simplification: Before multiplying, look for common factors between any numerator and denominator to reduce fractions early, making calculations easier.

Multiplying Fractions by Whole Numbers: Rewrite the whole number as a fraction over 1, then multiply as usual, using cross-cancelling to simplify if possible.

Multiplying Mixed Fractions: Convert mixed fractions to improper fractions before multiplying to avoid errors, as mixed fractions represent addition, not multiplication.
