Hi there!

The question is asking us to add the following fractions:


\sf{-(5)/(12)+\bigg(-(3)/(4)\bigg). We rewrite this as
\sf{-(5)/(12)-(3)/(4)}.

The next step is to find the LCD (Least common denominator). That is 12:


\sf{-(5)/(12)-(3*3)/(4*3)}


\sf{-(5)/(12)-(9)/(12)}

Simplify.


\sf{-(5+9)/(12)}=(14)/(12)}=(7)/(6)=1(1)/(6)}

The answer, as an improper fraction, is 7/6; as a mixed number, it is 1 + 1/6.

Have a fantastic day!
