Answer 1

I have a correct answer

Answer 2

$\Huge\mathfrak{{\orange{a}}{\blue{n}}{\pink{s}}{\purple{w}}{\red{e}}{\green{r}}:}$

$\bf{Let~the~unknown~number~be~‛x’}$

$\sf{~~~~~~{\dfrac{-7}{8}}-x={\dfrac{-5}{12}}}$

$\sf{:→ -x={\dfrac{-5}{12}}-{\dfrac{-7}{8}}}$

$\sf{:→ -x={\dfrac{(-10)-(-21)}{24}}}$

$\sf{:→ -x={\dfrac{-10+21}{24}}}$

$\sf{:→ -x={\dfrac{11}{24}}}$

$\sf\therefore{~~x=\color{red}{\underline{\boxed{\bf{\dfrac{-11}{24}}}}}}$
