The rational number project (rnp) is a research and curriculum development project involving multiple groups of faculty and graduate students from different universities interested in the teaching and learning of rational numbers. In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q.
