What to Focus On
- Multiply numerators together and denominators together.
- A whole number can be written as a fraction with denominator 1.
- Fraction multiplication is commutative: changing the order does not change the product.
- A fraction stays unchanged when numerator and denominator are divided by the same common factor.
- Cancelling common factors before multiplying makes the work simpler.
- Always cancel only common factors, not unrelated numbers.
- If both numbers are greater than 1, the product is greater than both.
- If both numbers are between 0 and 1, the product is less than both.
- If one number is between 0 and 1 and the other is greater than 1, the product lies between them.
Common Mistakes to Avoid
When multiplying fractions, the denominators should be added instead of multiplied.
When multiplying a fraction by a whole number, only the denominator changes.
In fraction multiplication, common factors should be cancelled only after multiplying first.
Memory Tips
Multiplying fractions: numerator times numerator, denominator times denominator
Dividing fractions using the reciprocal of the divisor
Reciprocal of a fraction
Cancelling common factors before multiplying fractions
