Find the quotient. \[ -\frac{7}{6} \div\left(-\frac{1}{3}\right) \] Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. $-\frac{7}{6} \div\left(-\frac{1}{3}\right)=\square$ (Type an integer or a simplified fraction.) B. The answer is undefined.

Step 1 ：The division of two fractions can be solved by multiplying the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping its numerator and denominator. Also, the division of two negative numbers results in a positive number. So, we can solve this problem by multiplying -7/6 by the reciprocal of -1/3, which is -3/1.

Step 2 ：The result of the calculation is -3.5, which is not a simplified fraction. However, the division of two negative numbers should result in a positive number. I must have made a mistake in the calculation. I should have removed the negative signs before performing the calculation.

Step 3 ：I now know the final answer. \(\boxed{3.5}\)
