Answer:


- (134)/(15)

Explanation:


-2(4)/(5) -6(2)/(15) =-\left( (2* 5)/(5) +(4)/(5) \right) -\left( (6* 15)/(15)+(2)/(15) \right)


-2(4)/(5) -6(2)/(15) =-\left( (10)/(5) +(4)/(5) \right) -\left( (90)/(15)+(2)/(15) \right)


-2(4)/(5) -6(2)/(15) =-\left( (14)/(5)\right) -\left( (92)/(15)\right)


-2(4)/(5) -6(2)/(15) =-\left( (42)/(15)\right) -\left( (92)/(15)\right)


-2(4)/(5) -6(2)/(15) =-\left( (42+92)/(15)\right)


-2(4)/(5) -6(2)/(15) =- (134)/(15)


-2(4)/(5) -6(2)/(15) =-8(14)/(15)
