Two Kinds of Real Numbers Rational Numbers Irrational Numbers

Rational Numbers A rational number is a real number that can be written as a ratio of two integers. A rational number written in decimal form is terminating or repeating.

Examples of Rational Numbers 16 1/2 3.56 -8 1.3333… - 3/4

Irrational Numbers An irrational number is a number that cannot be written as a ratio of two integers. Irrational numbers written as decimals are non-terminating and non-repeating.

Examples of Irrational Numbers Square roots of non-perfect “squares” Pi 17

Integers One of the subsets of rational numbers

What are integers? Integers are the whole numbers and their opposites. Examples of integers are 6 -12 0 186 -934

Identify which of the following are rational numbers 16 1/2 3.56 -28 0.2546…..25 74 3/5 250 0.252525…… 0.2456852….. -8 1.3333… - ¾ -2.232323….. 210 -5/6.000456 2.012546…. 15 0.25648….. 0.10101010….
