$4(\frac{5}{8}-2\frac{3}{4}(-\frac{7}{23}))-15(\frac{4}{5}(-\frac{7}{23})-2\frac{1}{3})-37.5\\\\4(\frac{5}{8}-\frac{11}{4}(-\frac{7}{23}))-15(\frac{4}{5}(-\frac{7}{23})-\frac{7}{3})-37.5\\\\4(\frac{5}{8}+\frac{77}{92})-15(-\frac{28}{115}-\frac{7}{3})-37.5\\\\4(\frac{269}{184})-15(-\frac{889}{345})-37.5\\\\\frac{269}{46}+\frac{13335}{345}-37.5\\\frac{2047}{46}-37.5\\\frac{89}{2}-37.5\\\frac{89}{2}-\frac{75}{2}\\=\frac{14}{2}=7$
