Answer 2

Answer:

$\frac{871}{105}$

Solve:

$\frac{16 }{5} + ( \frac{9}{2} - ( \frac{6}{7} \times \frac{1}{5} - \frac{1}{6})$

Step-by-step explanation:

Use this rule:

$\frac{a}{b} \times \frac{c}{d} = \frac{ac}{bd}$

$= \frac{19}{5} + \frac{9}{2} - ( \frac{6 \times 1}{7 \times 5} - \frac{1}{6} ) \\ = \frac{19}{5} + \frac{9}{2} - ( \frac{6}{7 \times 5} - \frac{1}{6} ) \\ = \frac{19}{5} + \frac{9}{2} - ( \frac{6}{35} - \frac{1}{6} ) \\ = \frac{19}{5} + \frac{9}{2} - \frac{1}{210} \\ = \frac{1792}{210} \\ = \frac{871}{105}$
