$- 1 + \frac{7}{11} \div \frac{17}{4} - \frac{1}{3}$

$- 1 + \frac{7}{11} \times \frac{4}{17} - \frac{1}{3}$

$- 1 + \frac{28}{187} - \frac{1}{3}$

$- \frac{664}{561}$

Answer 2

-1+(7/616+5/8):4 1/4-1/3

-1+(7/616+385/616): 17/4-1/3

-1+392/616:17/4-1/3

392/616=196/308=98/154=49/77=7/11

-1+7/11:17/4-1/3

-1+28/187-1/3

-187/187+28/187-1/3

-159/187-1/3

-477/561-187/561

-477-187/561=-664/561

-664/561=-1 103/561
