Answer:
solution given below
Step-by-step explanation:
Let the rational number be \frac{a}{b} .
Now, an equation can be formed.
Solve and find the value of \frac{a}{b} .
2( \frac{-7}{3} ) + \frac{a}{b} = \frac{3}{7}
\frac{-14}{3} + \frac{a}{b} = \frac{3}{7}
- \frac{14}{3} + \frac{a}{b} = \frac{3}{7}
\frac{a}{b} = \frac{3}{7} + \frac{14}{3}
\frac{a}{b} = \frac{107}{21}
∴ The required rational number is \frac{107}{21} .

Twice 4/3 = 8/3 => 56/21 ( lcm ).
Therefore 56-(-4)/21 = -60/21 should be added.
