\(-1,53:\left(5\dfrac{5}{28}-1\dfrac{8}{9}.1,25+1\dfrac{16}{63}\right)\)
\(=-1,53:\left(5\dfrac{5}{28}-\dfrac{17}{9}.\dfrac{5}{4}+1\dfrac{16}{63}\right)\)
\(=-1,53:\left(5\dfrac{5}{28}-\dfrac{17.5}{9.4}+1\dfrac{16}{63}\right)\)
\(=-1,53:\left(5\dfrac{5}{28}-\dfrac{85}{36}+1\dfrac{16}{63}\right)\)
\(=-1,53:\left(\dfrac{145}{28}-\dfrac{85}{36}+\dfrac{79}{63}\right)\)
\(=-1,53:\left(\dfrac{1305}{252}-\dfrac{595}{252}+\dfrac{316}{252}\right)\)
\(=-1,53:\dfrac{1305-595+316}{252}\)
\(=-1,53:\dfrac{1026}{252}\)
\(=\dfrac{-153}{100}:\dfrac{57}{14}\)
\(=\dfrac{-153}{100}.\dfrac{14}{57}\)
\(=\dfrac{-153.14}{100.57}\)
\(=\dfrac{-2142}{5700}\)
\(=\dfrac{-357}{950}\)
