Step-By-Step-Explanation

$-2\dfrac{23}{40} \: \: from -1\dfrac{7}{50}$

• Simplify it in standard form.

$~~~~~\implies~~ -\dfrac{103}{40} \: \: from -\dfrac{57}{50}$

$~~~~~\implies~~ \sf-\dfrac{57}{50} - \bigg(-\dfrac{103}{40} \bigg)$

$~~~~~\implies~~ \sf-\dfrac{57}{50} + \dfrac{103}{40}$

$~~~~~\implies~~ \sf \dfrac{103}{40} -\dfrac{57}{50}$

$~~~~~\implies~~ \sf \dfrac{515 - 228}{40}$

$~~~~~\implies~~ \sf \dfrac{287}{40}$

$\: \: \: \: \: \: \boxed{ \bf \frak{-2\dfrac{23}{40} \: \: from -1\dfrac{7}{50} =\huge{ \dfrac{287}{200} }}}$
