<h3>Answer: C) Multiplying 3 and 3</h3>

=================================================

Explanation:

When you multiply fractions, you multiply the numerators together. So in this case we multiply 3 and 3 getting 9 as the updated numerator.

We also multiply the denominators together. The updated denominator is 4*5 = 20.

Overall, (3/4)*(3/5) = (3*3)/(4*5) = 9/20

The fraction 9/20 cannot be reduced because 9 and 20 do not have any common factors other than 1.

We don't have to worry about getting the LCD (lowest common denominator) since that is only applicable for adding and subtracting fractions.
