The standard algorithm for multiplying fractions involves three primary steps:
Reduce the fraction to its simplest form by dividing both the numerator and denominator by their greatest common factor (GCF). Example: 3153 over 15 end-fraction can be simplified to 15one-fifth by dividing both by 3. Special Cases
Multiply the bottom numbers of each fraction together. This result becomes the new denominator. Example: For , calculate
