Answer:
morning, here is your answer
Step-by-step explanation:
a. -5/6, -4/5 - {to make denominatrs same}
= -5*5/6*5, -4*6/5*6 = -25/30, -24/30 {cross multiply}
= -25/30 + -24/30 { Minus + Minus = Minus}
= -25/30 - 24/30
= - 49/30
c. -15/26, 11/65 {to make denominatrs same}
= -15*65/ 26*65, 11*26/ 65*26 {cross multiply}
= -975/1690 + 286/1690
= -689/1690
I'm not sure if you have to simplify sorry... but if yes then u simplify plz
e. -9/16, 3/12 {to make denominatrs same}
= -9*12/16*12, 3*16/12*16 {cross multiply}
= -108/192 +48/192
= -60/192 simplified to -15/48
