 Section 1: Thought Question of the Week

 Is -15 a multiple of 5?

Name: Kennedy Clifford  Date: 2-10-10  Type of posting: 1  Posting: Brittany, you said that 5 is a //multiple// of -15, but 5 is actually a **factor**  of -15, not a multiple. **Factors are numbers you multiply together to get another number ****,** and in this case 5 and -3 are factors of -15 (**5** x **-3**= -15). The question asked if -15 is a multiple of 5 . ** A multiple is the result you get when multiplying by a whole number .** __Whole numbers are never fractions, decimals, or **negatives**__ and in this problem you would need to multiply by a negative number (-3) to get -15 (5 x **-3** = -15). In conclusion -15 is not a multiple of 5 because multiples need to be whole numbers, and in this case -15 is obviously not a whole number.

Name: Caroline McNally  Date: 2/10/10  Type of posting: 1  Posting: Hey guys, what wonderful weather we are having! -15 is not a multiple of 5. Kennedy, as you stated, a multiple is the answer you get when you multiply two whole numbers, and whole numbers can never be negative. This is a question that can be easily confused with FACTORS. Yes, 5 is a factor of -15, but that doesn't make -15 a multiple of 5. (:

Name: Jon Libock Date: 2/11/10 Type of posting: 1 Posting: Hey, I don’t think that 5 is a factor of -15. I think that because 5 have to be negative to be a factor of a negative number. So it would have to be -5 X 3 = -15.

Name: Hella Talas Date: 2/12/10 Type of posting: 1 Posting: Hey guys, I disagree, 5 is a multiple of -15. To get -15, you would **multiply** 5x-3. It does not matter if it is a negative number. Even though 5 and -3 are factors of -15, it does not mean that 5 is not a multiple of -15.

Like Juliet I was also confused looking at this problem. I do think that 5 is a factor of -15. For example, if you take -15 and factor it using a factor tree a set of numbers you can get is -3 and 5. I don't think 5 is a multiple of -15 becuase like Juliet said negative numbers aren't whole numbers**.

If 5 was multiplied by -3 it would then be -15. (-3 x 5 = -15). You can't multiply -15 by something to get 5, so -15 is not a multiple of 5.
