Answer

$\frac{-7}{2}$

Work Step by Step

Plug in and use PEMDAS (parentheses, exponentiation, multiplication, division, addition, subtraction) to determine which operation goes first. $\frac{-3}{1-\frac{1}{7}} = \frac{-3}{\frac{6}{7}} = \frac{-3\cdot7}{\frac{6}{7}\cdot7} = \frac{-21}{6} = \frac{-7}{2}$
