Answer 2

Answer:

$\frac{323}{210}$

Step-by-step explanation:

$\frac{4}{21} - (\frac{-5}{7}) + \frac{9}{5} + \frac{11}{6} - 3$

$\implies \frac{40}{210} + \frac{150}{210} + \frac{378}{210} + \frac{385}{210} - \frac{630}{210}$

$\implies \frac{40 + 150 + 378 +385 -630}{210}$

$\implies \frac{323}{210}$
