From Simple English Wik Get Started Rational Numbers Rational numbers are in the form of p/q, where p and q can be any integer and q ≠ 0. This means that rational numbers include natural numbers, whole numbers, integers, fractions of integers, and decimals (terminating decimals and recurring decimals).For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number. Likewise, any integer can be expressed as the ratio of two integers, thus all integers are rational. Now, some references. Dedekind used the letter R ( If you think you hear the word “fraction” when we say “rational number,” you are correct in your thinking. Any number that can be expressed as a fraction, where the numerator and denominator are integers, is a rational number. Every integer is also a rational number. Take, for example, the integer \(-12\). If x = 1 then x 2 = 1, but if x = –1 then x 2 = 1 also. Remember that the square of real numbers is never less than 0, so the value of x that solves x 2 = –1 can’t be real. We call it an imaginary number and write i = √ –1. Any other imaginary number is a multiple of i, for example 2 i or –0.5 i. Each publicly traded company that is listed on a stock...
