Best ResponseYou've already chosen the best response.1This is why the set of rational numbers is denoted \(\mathbb Q\) for quotient.

Best ResponseYou've already chosen the best response.1For any rational number there is a \(p\) and \(q\) with \(p,q\in\mathbb Z\) such that the rational number can be written as \(\dfrac p q \)

Best ResponseYou've already chosen the best response.0pi cannot be expressed as a quotient even though 22/7 is near therefore it is irrational

Best ResponseYou've already chosen the best response.1The simplest proof of an irrational number is the one for \(\sqrt2\). http://www.homeschoolmath.net/teaching/proof_square_root_2_irrational.php shows the standard proof, due to the Greeks.

Best ResponseYou've already chosen the best response.0the integers are 1, 2, 3, 0, 1, 2, 3, etc

Best ResponseYou've already chosen the best response.1Decimal numbers that terminate are rational, because they can be written as a fraction. For example, 2.231 can just be written as 2231/1000. This is the case for any decimal that terminates.

Best ResponseYou've already chosen the best response.0some decimals that dont terminate can also be expressed as fractions...for example 0.333333 can be expressed as 1/3

Best ResponseYou've already chosen the best response.11/3 is a quotient of two integers, so it is a rational number.

lgbasallote

Best ResponseYou've already chosen the best response.0that is rational because 1 amd 3 are integers

Best ResponseYou've already chosen the best response.1If you want to get even more fun you can look at the transcendental numbers, they are even more crazy than the irrational numbers. Irrational numbers that are not transcendental are called algebraic, they can be found as the roots of polynomials. There are all sorts of fun proofs to be read in this area of mathematics.

Best ResponseYou've already chosen the best response.1Also worth noting is that the union of the rational and irrational numbers forms the real numbers, \(\mathbb R\), which is the set that you usually work in. You can also go further to \(\mathbb C\), the complex numbers. And then even further than that :)

Best ResponseYou've already chosen the best response.01/3 has recurring digits but is still expressed as a quotient of two integers, so it is rational.
