Final answer:
The ratio of 33 to 45 simplifies to 11/15 after dividing by their greatest common divisor. Multiplying the original numbers gives 1485, while multiplying the simplified ratio (11 * 15) gives 165.
Step-by-step explanation:
The question asks to find the ratio of 33 to 45 and then to multiply these numbers. To find this ratio, we simply write it as 33/45. This can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which in this case is 3. So, simplifying we get 11/15. To multiply these numbers, you would simply calculate 33 * 45, equaling 1485.
However, this prompt might also be interpreted as multiplying 11 and 15 after simplifying the ratio, which would then be equal to 165.
