Given,
The sum of two rational numbers is -1.
One of the numbers is -5/7.
To Find,
The other number.
Solution,
The number that can be represented in the form of a/b where b ≠ 0 and a and b both are integers.
Let us assume that the other rational number is x.
So, according to the question
x-5/7 = -1
x = -1+5/7
x = (-7+5)/7
x = -2/7
Hence, the correct answer is option (b) -2/7.
