$\mathrm{\frac{-12}{16} \:, \:\frac{10}{-16}}$

$\mathrm{ -12 × -16 = \: \: 10 × 16 }$

$\mathrm{ 192 \neq \: \: 160 }$

${\blue{\boxed{\mathrm{ Hence,~\frac{-12}{16}\neq\frac{10}{-16} }}}}$

$\mathrm{\frac{-15}{20} \:, \:\frac{25}{-30}}$

$\mathrm{ -15~×~-30 = \: \: 25~×~20}$

$\mathrm{ 450 \neq \: \: 500 }$

${\blue{\boxed{\mathrm{ Hence,~\frac{-15}{20}\neq\frac{25}{-30}}}}}$

$\mathrm{\frac{-8}{24} \:, \:\frac{7}{-21}}$

$\mathrm{ -8~×~-21 = \: \: 24~×~7}$

$\mathrm{ 168 = \: \: 168 }$

${\blue{\boxed{\mathrm{ Hence,~\frac{-8}{24}=\frac{7}{-21}}} }}$

$\mathrm{\frac{-6}{-10} \:, \:\frac{11}{-15}}$

$\mathrm{ -6~×~-15= \: \: -10~×~11}$

$\mathrm{90 \neq\: \: -110 }$

${\blue{\boxed{\mathrm{ Hence,~\frac{-6}{-10}\neq\frac{11}{-15} }}}}$⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
