Okay
Times the demominators 5 and 3 = 15
What do i time 3 by to get 15 = 5
so -2/3 becomes -10/15
What do I times 5 by to get 15 =3
so -4/5 becomes -12/15
Now I have -10/15 + -12/15 = -22/15
Can't be simplified so the answer is
-22/15 or -1 and 7/15

Is this what you are trying to say ?
-2 over three + -4 over 5
= (-2/3) + (-4/5)
= (-2/3)*(5/5) + (-4/5)*(3/3)
= (-10/15) + (-12/15)
= -22/15
I hope on "your" homework-help website you explain things more clearly.
