Question

Which rational number should be added to minus 5 by 9 to get minus 2 by 3

Answer 1

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.
