Answer:
Explanation:
Given that the highest common factor (HCF) of two numbers is 3, and one of the numbers is 9, we can find the possible values of the other number by considering the relationship between the HCF and the numbers themselves.
The HCF of two numbers is the largest positive integer that divides both numbers evenly. Since the HCF of the two numbers is 3, the other number must also be divisible by 3.
Given that one of the numbers is 9 (which is divisible by 3), the possible values for the other number that satisfy the given conditions are any positive integer multiples of 3. This means the other number could be 3, 6, 9 (which is the given number), 12, 15, 18, and so on.
In summary, the possible values for the other number are any positive integer multiples of 3.
