Question

The Product of two rational number is 5/8.If one of them is -3/18,find the other

Answer 1

Given

$\bold{Product \ of \ 2 \ rational \ numbers} = \dfrac{5}{8}$

$\bold{One \ of \ the \ rational \ number} = \dfrac{-3}{18}$

Let the other rational number be x.

$\implies \dfrac{-3}{18} x = \dfrac{5}{8}$

$\implies x = \dfrac{5}{8} * \dfrac{18}{-3}$

$\implies x = \dfrac{5}{4} * \dfrac{9}{-3}$

$\implies x = \dfrac{45}{-12}$

$\implies x = \dfrac{-15}{4}$

$\boxed{\boxed{\bold{Therefore, \ the \ other \ number \ is \ \frac{15}{4}}}}}}$
