Answer:
Answer: -1/9
Step-by-step explanation:
To find what should be added to a to get c we should subtract c with a to get b, a+b=c therefore b=c-a
Similarly,+( -5/9)+x=-2/3
x=-2/3-(-5/9)
x=-2/3+5/9
x=-6+5/9 [multiplying common LCM to both numerator and denominator]
Therefore, x=-1/9
Verification
-5/9+(-1/9)=-6/9=-2/3
Hence, -1/9 is the number which is to be added.
