Rational Numbers Rational Numbers: a number that can
be written in fractional form, a/b where a and b are integers and b ≠ 0

Types of decimal forms
Terminating Decimal– if the quotient ha a remainder of zero
Repeating Decimal—if the quotient has a digit or group of digits that repeat without end

Additive Inverse Property Additive Inverse (opposites) – two rational numbers that are the same distance from zero on the number line, but on opposite sides of zero The sum of a rational number and
its additive inverse is 0 Examples
