Rational number
the number of the form a/b,where a and b are integer and b is not equal to zero ,are called rational number
Example-Each of the numbers 5/8,-3/14,-7/15 and -6/-11
positive rational number:-A rational number is said to be positive if its numerator and denumerator are either both positive or both negative.
thus,4/9 and -5/-12 are both positive rationals.
Negative rational number:-A rational number is said to be negative if its numerator or denumerator are opposite signs.
thus,-4/9 and 5/-12 are both negative rationals.
Three properties of rational number:-
Standard form of a rational number:
A rational number a/b is said to be in satndard form if a and b are integers having no common divisior other than 1 and b is positive.
Camparison of Rational numbers.
it is clear that
(1) every positive rational number is greater than 0.
(2)every negative rational number is less than 0.
General method of camparing Numbers
step (1) Express each of the two given rational number positive
represent the following rational numbers on a number linethus,-4/9 and 5/-12 are both negative rationals.
