Answer

(i) We have:

$\dfrac{12}{17}$

Numerator = 12, Denominator = 17

(ii) We have:

$\dfrac{6}{-23}$

Numerator = 6, Denominator = -23

(iii) We have:

$\dfrac{-21}{5}$

Numerator = -21, Denominator = 5

(iv) We have:

It can be written as $\dfrac{7}{1}$

Numerator = 7, Denominator = 1

(v) We have:

-8

It can be written as $\dfrac{-8}{1}$

Numerator = -8, Denominator = 1
