    \huge\mathfrak\blue{Answer:}

    Rational Number:

    • Rational Number are the numbers that can be written in the form of a/b where a and B are integers and b is not equal to zero
    • For ex : 2/3 , 3/5 , 5/7 etc

    Solution:

    We have to subtract the given rational number from one another

    \odot \: \boxed{\sf{Subtracting \: \dfrac{-2}{3} \: from \: \dfrac{6}{7}}}

    • \mapsto \sf{\dfrac{6}{7} - \left ( \dfrac{-2}{3} \right ) }
    • \mapsto \sf{\dfrac{6}{7} + \dfrac{2}{3} }
    • Taking LCM on RHS
    • \mapsto \sf{\dfrac{6 \times 3 + 2 \times 7}{21} }
    • \mapsto \sf{\dfrac{18 + 14}{21} }
    • \mapsto \sf{\dfrac{32}{21} \: \: }✔

    \sf{ }

    Moving to the next Question which is :

    \odot \: \boxed{\sf{Subtracting \: \dfrac{3}{-11} \: from \: \dfrac{-1}{11}}}

    • \mapsto \sf{\left ( - \dfrac{1}{11} \right ) - \left ( -\dfrac{3}{11} \right ) }
    • \mapsto \sf{\dfrac{3}{11} - \dfrac{1}{11} }
    • \mapsto \sf{\dfrac{2}{11} \: \: }✔

    \sf{ }

    Moving to the next Question which is :

    \odot \: \boxed{\sf{Subtracting \: \dfrac{-4}{-7} \: from \: \dfrac{3}{-7}}}

    • \mapsto \sf{\left ( \dfrac{3}{-7} \right ) - \left (\dfrac{-4}{-7} \right ) }
    • \mapsto \sf{\dfrac{3}{7} -\dfrac{4}{7} }
    • \mapsto \sf{-\dfrac{1}{7} \: \: }✔
