Final answer:
The solution to (r/s) multiplied by 3 is (3r/s), where you multiply the numerator by 3 and leave the denominator unchanged.
Step-by-step explanation:
The question seems to refer to multiplying a fraction (r/s) by 3. To solve this, you essentially need to multiply the numerator (which is 'r' in this case) by the whole number (which is '3' here), while the denominator ('s') remains the same. Hence, the solution to (r/s) * 3 is (3r/s). This type of operation is common in algebra and represents basic principles of multiplying fractions by whole numbers.
