When multiplying fractions, we multiply the numerators together to obtain the numerator of the result, and multiply the denominators together to obtain the denominator of the result. After this, we simplify the fraction by eliminating any common factors from the numerator and the denominator.
Alternatively, we can first cancel out any common factors between the numerators and the denominators of the fractions before performing the multiplication. This method can save time and effort.
Both 30 and 85 have a common factor of 5. We can simplify the fraction by dividing both the numerator and the denominator by 5, resulting in .
