Find the multiplicative inverse (reciprocal) of each of the following rational numbers:

(i) 9


(ii) -7


(iii)


(iv)


(v)


(vi)


(vii)


(viii)


(ix) -1


(x)


(xi)1

(i) Reciprocal of 9 is

(ii) Reciprocal of –7 is


(iii) Reciprocal of is


(iv) Reciprocal of is


(v) Reciprocal of is


(vi) * =


Reciprocal of is


(vii) * =


Reciprocal of is


(viii) -2 * =


Reciprocal of is


(ix) Reciprocal of -1 is -1


(x) Reciprocal of is not defined as in the form of , q = 0, so it is not a rational number


(xi) Reciprocal of 1 is 1
