Integers on page 33 in guide 6

[rachelserkez1]

Hello,
I am in the Quantitative Comparisons and Data interpretation guide 6, pg 33. I don't understand why the explanation at the top pf the page says "because y is an integer, you know that you do not need to try positive and negative fractions." What does that mean? Aren't integers both positive and negative?
Thanks,
Rachel

Integers are, by definition, not fractions. So if you know y is an integer, it can't be a fraction (either positive or negative).

-t

P.S. I deleted the previous response post made by a forumgoer because I think it was needlessly confusing.
