Rational and Irrational Numbers

2
Standards: Use properties of rational and irrational numbers. MGSE9–12.N.RN.2 Rewrite expressions involving radicals (i.e., simplify and/or use the operations of addition, subtraction, and multiplication, with radicals within expressions limited to square roots). MGSE9–12.N.RN.3 Explain why the sum or product of rational numbers is rational; why the sum of a rational number and an irrational number is irrational; and why the product of a nonzero rational number and an irrational number is irrational.

3
EQ: Why is the sum or product of rational numbers rational? Why is the sum of a rational number and irrational number irrational? Why is the product of a nonzero rational number and an irrational number irrational?

Definition: Rational Numbers A number expressible in the form a/b or – a/b for some fraction a/b. The rational numbers include the integers Irrational Numbers A number whose decimal form is nonterminating and nonrepeating. Irrational numbers cannot be written in the form a/b, where a and b are integers (b cannot be zero). So all numbers that are not rational are irrational.
