Given: Rational numbers-

$(i)$. $\frac{-8}{6}$

$(ii)$. $\frac{25}{45}$ 

$(iii)$. $\frac{-44}{72}$

$(iv)$. $\frac{-8}{10}$


To do:

We have to write the given rational numbers in the simplest form.

Solution:

$(i)$. $\frac{-8}{6}$

$=\frac{2\times(-4)}{2\times3}$

$=\frac{-4}{3}$

$(ii)$. $\frac{25}{45}$

$=\frac{5\times5}{5\times9}$

$=\frac{5}{9}$

$(iii)$. $\frac{-44}{72}$

$=\frac{4\times(-11)}{4\times18}$

$=\frac{-11}{18}$ 

$(iv)$. $\frac{-8}{10}$

$=\frac{2\times(-4)}{2\times5}$

$=\frac{-4}{5}$
