Rational numbers - practice problems - page 6 of 20
a rational number is a number that can be expressed as the fraction p/qof two integers, a numerator p and a non-zero positive denominator q. The decimal expansion of a rational number either terminates after a finite number of digits (example: 1/2 = 0.5), or eventually begins to repeat the same finite sequence of digits over and over - example 1/3 = 0.33333....
