Question

Premise: All multiples of 9 are multiples of 3. Premise: 57 is a multiple of 3. Conclusion: 57 is a multiple of 9.

Answer 1

The conclusion is false.

Explanation:

`(57)/(3) = 19\\\\(9)/(3) = 3`

Although 3 and 9 do share some multiples, they must be divisible by 3. For example. 36/3 = 12, and 12 is divisible by 3. However, 57/3 = 19, which is not divisible by 3.
