#### 1. Fill in the blanks :

(i) The multiplicative inverse of a rational number is also called its reciprocal.

(ii) Every negative rational number is less or smaller than 0.

(iii) A rational number (p/q) is said to be in standard form, if q is positive and p and q have no common divisor other than 1.

(iv) (-5/-9) is a positive rational number.

(v) The additive inverse of a rational number (a/b) is (-(a/b)).

#### 2. Write true (T) or false (F) :

 Statement True/False (i) There exists a rational number which is neither positive nor negative. T (ii) Every rational number has a multiplicative inverse. F (iii) Every rational number when expressed in its standard form has its denominator greater than the numerator. F (iv) The sum of a rational number and its additive inverse is always. T (v) The product of a rational number and its multiplicative inverse is always. T (vi) Any tow equivalent rational number have the same standard form. F (vii) The product of any two rational number is also a rational number. T (viii) A rational number when divided by another rational number always given a rational number. T (ix) Every rational number smaller than a given rational number (p/q) lie to the left of (p/q). F
