\huge \boxed{\mathfrak{Question} \downarrow}

  • Find the value of 'k' in the question given.


\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}


\large \sf- \frac { 7 } { 6 } = - \frac { 1 } { 3 } k \\

  • Multiply both sides by -3, the reciprocal of
    \sf-(1)/(3).


\large \sf-(7)/(6)\left(-3\right)=k \\

  • Express
    \sf -(7)/(6)\left(-3\right) as a single fraction.


\large \sf(-7\left(-3\right))/(6)=k \\

  • Multiply -7 and -3 to get 21.


\large \sf(21)/(6)=k \\

  • Reduce the fraction
    \sf(21)/(6) to its lowest terms by extracting and cancelling out 3.


\large \sf(7)/(2)=k \\

  • OR


\large \boxed{ \bf \: k = (7)/(2) = 3(1)/(2) = 3.5}

  • NOTE :- Yes, your assumption is right. 'k' is the number which should be multiplied by -1/3 in order to get -7/6.
