Could you clarify please what you don't understand or what's confusing you? The more we know the easier it is to help.jmartin wrote:After reading the explanation for the correct answer I still don't understand it. I feel that I'm missing something.

The answer that was given was 1/3. How do you get this answer? Part of the explanation is "only one-third of all whole numbers are multiples of 3". Is this knowledge that I should have already or was there a formula used to get this answer?

Hi,

Sorry for the delayed response. I would say that your question requires outside knowledge, but more in a logical sense than in a content, formula-based sense. The statement that only 1/3 numbers are multiples of three makes sense logically, because the multiples of three are:

3, 6, 9, 12, ...

and the non-multiples of three are:

1, 2, 4, 5, 7, 8, 10, 11, ...

So, in the same space on the number line, four out of twelve numbers are multiples of three and eight out of twelve are not. Thus, one third of whole numbers are multiples of three.

I hope this helps!

Will
