Answer 1

Answer:

    $-\frac{323}{14}$ or, $-23\frac{1}{14}$

Step-by-step explanation:

$\frac{-4}{7}$ + 7 [  $\frac{-3}{14}$  -  {  $\frac{2}{5}$  of  $\frac{-15}{8}$  ÷  $\frac{-1}{4}$  } ]

= $\frac{-4}{7}$ + 7 [  $\frac{-3}{14}$  -  {  $-2$  of $\frac{3}{8}$  ÷  $\frac{-1}{4}$  } ]

=  $\frac{-4}{7}$ + 7 [  $\frac{-3}{14}$  -  {  $-\frac{3}{4}$ ÷  $\frac{-1}{4}$  } ]

=  $\frac{-4}{7}$ + 7 [  $\frac{-3}{14}$  -  {  $\frac{3}{4}$ ÷  $\frac{1}{4}$  } ]

=  $\frac{-4}{7}$ + 7 [  $\frac{-3}{14}$  -  {  $\frac{3}{4}$  ×  $4$  } ]

=  $\frac{-4}{7}$ + 7 [  $\frac{-3}{14}$  -  {  3 } ]

=  $\frac{-4}{7}$ + 7 [  $\frac{-3}{14}$  -  3  ]

=   $\frac{-4}{7}$ + 7 [  $-\frac{45}{14}$   ]

=  $\frac{-4}{7}$ - 7 × $\frac{45}{14}$  

=    $\frac{-4}{7}$ -  $\frac{45}{2}$  

=  $-\frac{323}{14}$ or, $-23\frac{1}{14}$             (ANS)
