$1 frac{6}{5} times 2 frac{8}{9} - 2.7 times 1 frac{1}{8}$

$= 3 frac{59}{90} times 1 frac{1}{8}$

$= frac{3 times 90 + 59}{90} times frac{1 times 8 + 1}{8}$

$= frac{329}{90} times frac{9}{8}$

$= frac{329 times 9}{90 times 8}$

$= frac{2961}{720}$

$= frac{329 times 9}{80 times 9}$

$= frac{329}{80}$

$= frac{4 times 80 + 9}{80}$

= $4 frac{9}{80}$
