Question

6. Find the reciprocal of the following rational numbers:

(a) -3/4. (b) 0. (c) 6/11. (d) 5/-9​

Answer 1

Answer:

(1) -4/3

(2) 0

(3) 11/6

(4) 9/-5

Answer 2

Reciprocals are (a) -4/3, (b) Undefined, (c)11/6, (d) -9/5

Given: Rational numbers (a) -3/4, (b) 0, (c) 6/11, (d) 5/-9

To Find: Reciprocal of the given numbers

Solution:

We know that, the rational number obtained after exchanging the numerator and denominator is called the reciprocal of the rational number. It means reciprocal of N/D = D/N

(a) Reciprocal of -3/4 = -4/3

(b) Reciprocal of 0 = 1/0 which means undefined.

(c) Reciprocal of 6/11 = 11/6

(d) Reciprocal of 5/-9 = -9/5

So, reciprocals are (a) -4/3, (b) Undefined, (c)11/6, (d) -9/5
