How to calculate fractions multiplied by fractions:

To multiply a fraction by a fraction, use the product of the numerators as the numerator and the product of the denominators as the denominator.

(Note: Those that can be reduced must be reduced first, and the result must be the simplest fraction)

Determining whether the product in fractional multiplication is greater, smaller, or equal to one multiplier depends on the other multiplier. If the other multiplier is less than 1, the product is less than this multiplier; if the other multiplier is greater than 1, the product is greater than this multiplier; if the other multiplier is equal to 1, the product is equal to this number.
