Hi Rebecca.

We have a glossary of mathematical terms that you might find a useful bookmark. It is here:
mathcentral.uregina.ca/RR/glossary/middle/glossaryr.html

(That's the R page, where we talk about rational numbers.)

Positive rationals are rational numbers larger than zero. For example, a positive integer over another positive integer or a negative integer over another negative integer is always a positive rational number.
