☆VERIFIED ANSWER ☆

BY ADDING WE GET THIS :~

= -3/4 + (-5/12)

= -3/4 -5/12

= -14/12

= -7/6 ( EQUATION 1).......(i)

BY MULTIPLYING WE GET ••••••

-3/4 × -5/12

= 5/16( EQUATION 2).......(ii)

FROM BOTH THE EQUATIONS WE CONCLUDE

EQUATION 1 AND EQUATION 2

DIVIDING THEM GIVES THE RESULT AS

-7/6 ÷ 16/5

= -112/30
