[Ngọc Lưu]

\(a.=\left(\frac{153}{37}-\frac{19}{5}+\frac{199}{23}\right)-\left(\frac{116}{37}-\frac{188}{29}\right)\)

\(=\frac{153}{37}-\frac{19}{5}+\frac{199}{23}-\frac{116}{37}+\frac{188}{29}\)

\(=\frac{37}{37}-\frac{19}{5}+\frac{199}{23}+\frac{188}{29}\)tự giải tiếp ^^

\(b.=\frac{8}{3}.\frac{-15}{4}.\frac{4}{5}\)

\(=\frac{8.\left(-15\right).4}{3.4.5}\)

\(=\frac{-480}{60}=-8\)
