$\Rightarrow - 7 (\frac{11}{56})$ $color(cyan)(=> - 7 (11/56)$

$- 11 (\frac{5}{8}) - (- 4 (\frac{3}{7})$ $-11(5/8) - (-4(3/7)$

$\Rightarrow - \frac{93}{8} - (- \frac{31}{7})$ $=> -93/8 - (-31/7)$

$- \frac{93}{8} + \frac{31}{7}$ $-93/8 + 31/7$

L C M of 7,8 is 7*8 = 56

$\Rightarrow \frac{(- 93 \cdot 7) + (31 \cdot 8)}{56}$ $=> ((-93 * 7) + (31*8)) / 56$

$\Rightarrow \frac{- 651 + 248}{56}$ $=> (-651 + 248) / 56$

$\Rightarrow - \frac{403}{56}$ $=> -403 / 56$

$\Rightarrow - 7 (\frac{11}{56})$ $color(cyan)(=> - 7 (11/56)$
