Step-by-step explanation:

$=\frac{60}{53}*[\frac{6}{5}-[\frac{19}{5}/(\frac{1}{2}+\frac{1}{3})]*\frac{15}{4}]\\\\\\=\frac{60}{53}*[\frac{6}{5}-[\frac{19}{5}/(\frac{3+2}{6})]*\frac{15}{4}]\\\\\\=\frac{60}{53}*[\frac{6}{5}-[\frac{19}{5}/\frac{5}{6}]*\frac{15}{4}]\\\\\\=\frac{60}{53}*[\frac{6}{5}-[\frac{19}{5}*\frac{6}{5}]*\frac{15}{4}]\\\\\\=\frac{60}{53}*[\frac{6}{5}-\frac{114}{25}*\frac{15}{4}]\\\\\\=\frac{60}{53}*[\frac{6}{5}-\frac{57}{5}*\frac{3}{2}]\\\\\\=\frac{60}{53}*[\frac{6}{5}-\frac{171}{10}]$

$=\frac{60}{53}*[\frac{12}{10}-\frac{171}{10}]\\\\\\=\frac{60}{53}*[\frac{12-171}{10}]\\\\\\=\frac{60}{53}*\frac{-159}{10}\\\\\\=\frac{6}{1}*\frac{-3}{1}\\\\\\=\frac{-18}{1}\\\\\\=-18$
