b) -117/36
c) -78/36
d) -96/36​

Answer 1

➤ Answer :-

$\tt \dfrac{13}{( - 4)} = \dfrac{?}{36}$

To find the value of the numerator, we have to divide 36 and (-4), then multiply with 13.

$\tt \dfrac{36}{( - 4)} \times 13$

$\tt \cancel \dfrac{36}{( - 4)} \times 13 = ( - 9) \times 13$

$\tt? = - 117$

$\tt \dfrac{13}{( - 4)} = \dfrac{( - 117)}{36}$

So, the rational number is :-

$\tt \dfrac{( - 117)}{36}$

$\Huge\therefore$Option (B) $\tt\dfrac{(-117)}{36}$ is the correct answer.
