Answer 1

Answer :-

$\star \: \bf \dfrac{17}{35}$

Step-by-step-Explaination :-

$\dfrac{3}{5} + \dfrac{12}{7} + \dfrac{ - 7}{5} + \dfrac{ - 3}{7}$

$\rm \longmapsto\dfrac{3}{5} + \dfrac{12}{7} - \dfrac{ 7}{5} - \dfrac{ 3}{7}$

$\rm \longmapsto\dfrac{3}{5} - \dfrac{ 7}{5} - \dfrac{ 3}{7} + \dfrac{12}{7}$

$\rm \longmapsto\dfrac{3 - 7}{5} + \dfrac{12 - 3}{7}$

$\rm \longmapsto\dfrac{-4}{5} + \dfrac{9}{7}$

Finding L.C.M of 5 and 7 that is 35 .

$\rm \longmapsto\dfrac{-28 + 45}{35}$

$\rm \longmapsto\dfrac{17}{35}$

$\rm{ \huge \therefore} \: \bf \dfrac{17}{35}\: is \: the \: answer$
