## Questions & Answers

### Q: What is cancellation in multiplication of fractions?

Cancellation refers to the process of identifying common factors between the numerators and denominators of fractions being multiplied and simplifying them as you go along. This simplifies the final fraction and makes calculations easier.

### Q: How does cancellation make multiplication of fractions easier?

Cancellation eliminates the need to find common factors after multiplying the numerators and denominators. By simplifying as you go, the resulting fraction is already in its simplest form, saving time and effort.

### Q: Can cancellation be applied to fractions with different denominators?

Yes, cancellation can be applied to fractions with different denominators. The process involves identifying common factors between the numerators and denominators, simplifying them, and then multiplying to get the final answer.

### Q: Are there any limitations to using cancellation in multiplying fractions?

The main limitation of cancellation is that it can only be applied when there are common factors between the numerators and denominators. If no common factors exist, cancellation cannot be used to simplify the fractions further.

## Summary & Key Takeaways

• The video demonstrates the concept of cancellation in multiplying fractions, where common factors are identified and simplified as you go along.

• By cancelling common factors, the multiplication process becomes simpler and the resulting fraction is easier to work with.

• Several examples are provided to illustrate the cancellation technique, showing how it can be applied to different fraction multiplication problems.
