We have proved that the square root of two is not a rational number.

In theory, therefore, any rational number can be expressed with a single mark on a bar of metal.

A ratio makes a rational number?

In this study, college students completed a rational number magnitude task, procedural arithmetic tasks in fraction and decimal notation, and an algebra assessment.

Recent research suggests that fraction understanding is predictive of algebra ability; however, the relative contributions of various aspects of rational number knowledge are unclear.

For this reason, they are often called the rational numbers or rationals for short.

Therefore, the group of odd over even rational numbers cannot have the square root of two in it!

Integers, on the other hand, are rational numbers because they can be thought of as fractions whose denominators are 1.

As any student of maths can tell you, while the real numbers are uncountable, the rational numbers are indeed a countable set.

In your journey from one end to the other you'll encounter the rational numbers and the irrational numbers, most notably the transcendentals.

Boy: We want to see if this square root of two we discovered the other day is a member of the rational numbers?

We develop a model similar to a bilayer fractional quantum Hall system valid near simple rational numbers of magnetic flux quanta per lattice cell.

Furthermore, whether this relationship is notation-dependent or rather relies upon a general understanding of rational numbers (independent of notation) is an open question.
