b) 3
c) 0
d) 9
3​

Answer 1

Question :-

Reciprocal of 3 is -

(a) $\frac{1}{3}$

(b) 3

(c) 0

(d) 9

Solution :-

Every Non - Zero Rational Number $\frac{a}{b}$ has its Multiplicative Inverse (Reciprocal) $\frac{b}{a}$ .

Thus, $\bold {(\frac{a}{b} \times \frac{b}{a}) = (\frac{b}{a} \times \frac{a}{b}) = 1}$

$\frac{b}{a}$ is called the Reciprocal of $\frac{a}{b}$

-----

Reciprocal of 3 is $\bold {\frac{1}{3}}$, since $(\frac{3}{1} \times \frac{1}{3}) = (\frac{1}{3} \times \frac{3}{1}) = \bold 1$ .

∴ Option A is the Right Answer . . .
