$(12.25-2\frac{17}{20} +2\frac{2}{9} *(-6.3)):3\frac{1}{5} +4\frac{3}{4} =(\frac{49}{4} -\frac{57}{20} +\frac{20}{9} *(-\frac{63}{10} )):\frac{16}{5} +\frac{19}{4} =\\\\=(\frac{49}{4} -\frac{57}{20} -14)*\frac{5}{16} +\frac{19}{4} =(\frac{245}{20} -\frac{57}{20} -\frac{280}{20} )*\frac{5}{16} +\frac{19}{4} =-\frac{92}{20} *\frac{5}{16} +\frac{19}{4} =\\\\=-\frac{23}{16} +\frac{19}{4} =-\frac{23}{16}+\frac{76}{16} =\frac{53}{16} =3\frac{5}{16}$

$3\frac{5}{16} *0.16=\frac{53}{16} *\frac{16}{100} =\frac{53}{100} =0.53$
