A. Yes, it is reasonable because 33, 63, and 93 are all divisible by 3. B. Yes, it is reasonable because a number that ends in 3 will always be odd. C.No, it is not reasonable because 13 is not divisible by 3. D.No, it is not reasonable because 6, 9, and 12 do not end in 3.

For any number to be divisible by 3, all integers of the number have to add up to a multiple of 3. For example 81 is divisible by 3 because 8+1=9

3 is divisible by 3 but 13 is not. Divisible in this context means the remainder is 0. I am interpreting "reasonable" to mean "true." C. No, it is not reasonable because 13 is not divisible by 3.

It has to hold for ALL cases, not just 1.
