\(\frac{33}{5}\times\frac{3}{8}-\frac{3}{8}:\frac{5}{3}-\frac{5}{4}\)
\(=\frac{33}{5}\times\frac{3}{8}-\frac{3}{8}\times\frac{3}{5}-\frac{5}{4}\)
\(=\frac{3}{8}\times\left(\frac{33}{5}-\frac{3}{5}\right)-\frac{5}{4}\)
\(=\frac{3}{8}\times2-\frac{5}{4}\)
\(=\frac{3}{4}-\frac{5}{4}\)
\(=-\frac{1}{2}\)
\(\frac{33}{5}\)x\(\frac{3}{8}\)- \(\frac{3}{8}\):\(\frac{5}{3}\)- \(\frac{5}{4}\)= (\(\frac{33}{5}\)x \(\frac{3}{8}\)) - ( \(\frac{3}{8}\): \(\frac{5}{3}\)) - \(\frac{5}{4}\)= \(\frac{99}{40}\)- \(\frac{9}{40}\)- \(\frac{5}{4}\)= \(\frac{90}{40}\)- \(\frac{5}{4}\)= \(\frac{9}{4}\)- \(\frac{5}{4}\)= \(\frac{4}{4}\)= 1
