Answer:


\displaystyle{ - (9)/(6) + ( - (3)/(5) ) }


\displaystyle{ - (9)/(6) - (3)/(5) }

  • Multiply the numerator and denominator to make it equivalent:


\displaystyle{ = - (9)/(6) = - (9 * 5)/(6 * 5) = - (45)/(30) }


\displaystyle{ = (3)/(5) = (3 * 6)/(5 * 6) = (18)/(30) }

So,


\displaystyle{ = - (45)/(30) - (18)/(30) = - (45 - 18)/(30) = - (37)/(30) }
