Answer 2

Given: The sum of two rational numbers is$-5/6$. one of them is$-2/3$.

We have to find the other rational number.

We are solving in the following way:

We have,

The sum of two rational numbers is$-5/6$. one of them is$-2/3$.

Let assume the other number will be$x$.

Then, from the above statement, we can write:

$=>-\frac{2}{3} +x=-\frac{5}{6}$

$=>x=-\frac{5}{6} +\frac{2}{3} \\\\=>x=\frac{-5\times3+2\times6}{6\times3} \\\\=>x=\frac{-15+12}{18} \\\\=>x=\frac{-3}{18} \\\\=>x=-\frac{1}{6}$

Hence, the other rational number will be$-\frac{1}{6}$.
