Multiply Fractions: Learn
To Multiply Fractions:
- Multiply the numerators of the fractions
- Multiply the denominators of the fractions
- Place the product of the numerators over the product of the denominators
- Simplify the Fraction
Example: Multiply 2/9 and 3/12
That last step can be tough, simplifying a fraction with big numbers. To keep the numbers small and easy to work with, you can cancel factors before multiplying. It's the same as simplifying a fraction, but you can choose the numerator and denominator of either fraction.
Example: Multiply 2/9 and 3/12, but first simplify the problem by canceling a factor of 3 out of the 3 and 9, and also canceling out a factor of 2 from the 2 and 12.
