We will learn about the positive rational number.
A rational number is said to be positive if its numerator and denominator are either both positive integers or both negative integers.
In other words, a rational number is positive, if its numerator and denominator are of the same sign.
Each of the rational numbers 1/4, 2/9, -7/-11, -3/-13, 5/12 are positive rationals, but 2/-5, -3/10, -4/7, 11/-23 are not positive rationals.
1. Is every natural number a positive rational number?
We know that, 1 = 1/1, 2 = 2/1, 3 = 3/1, 4 = 4/1 and so on ……..
In other words, any natural number n can be written as n = n/1, where n and 1 are positive integers.
Hence, every natural number is a positive (+ve) rational number.
Note: The rational number 0 is neither positive nor negative.
2. Determine whether the following rational numbers are positives or not:
(i) (-11)/3
(-11)/3 is not a positive rational. Since both the numerator and denominator are of the opposite sign.
(ii) (-5)/(-7)
(-5)/(-7) is a positive rational. Since both the numerator and denominator are negative integers.
(iii) 13/19
13/19 is a positive rational. Since both the numerator and denominator are positive integers.
(iv) 21/(-17)
21/(-17) is not a positive rational. Since both the numerator and denominator are of the opposite sign.
(v) (-105)/(-8)
(-105)/(-8) is a positive rational. Since both the numerator and denominator are negative integers.
(vi) (-3)/7
(-3)/7 is not a positive rational. Since both the numerator and denominator are of the opposite sign.
(vii) 27/31
27/31 is a positive rational. Since both the numerator and denominator are positive integers.
(viii) 25/(-27)
25/(-27) is not a positive rational. Since both the numerator and denominator are of the opposite sign.
So, from the above explanation we conclude that a rational number is positive, if its numerator and denominator are of the same sign.
