A rational number is a number which can be expressed as a fraction whose numerator and denominator are both integers and whose denominator is not equal to zero. Rational numbers include all integers, fractions, mixed numbers, and some decimal numbers.
Note : All terminating and repeating decimal numbers are rational numbers because those numbers can be expressed as a fraction. On the other hand, a non repeating number and non terminating decimal, like square root of 2, is an irrational number.
Rational numbers can be arranged in order on a number line.
The smaller numbers are on the left side. The largest numbers are on the right. The symbols to express there are
Larger ( greater ) then = >
Smaller (less) then = <
