Answer:
-19/30
Step-by-step explanation:
First we add -2/3+(-4/5)
-2/3+(-4/5)=
We need to find the LCM by doing listing method
3=3,6,9,12,15=5
5=5,10,15=3
-2/3* 5/5= -10/15
-4/5*3/3= -12/15
-10/15+-12/15= 22/15 or
-1 7/15
But we need to still let it be improper
-22/15+5/6
LCM again
15=15,30=2
6=6,12,18,24,30=5
-22/15*2/2= 44/30
5/6*5/5=25/30
-44/30+25/30=19/30
-19/30
