\(\frac{4}{3}\div\text{x}=\frac{-5}{2}\)
\(\Rightarrow\) \(\text{x}=\frac{4}{3}\div\frac{-5}{2}\)
\(\Rightarrow\) \(\text{x}=\frac{4}{3}\times\frac{2}{-5}\)
\(\Rightarrow\) \(\text{x}=\frac{4\times2}{3\times-5}\)
\(\Rightarrow\) \(\text{x}=\frac{8}{-15}=\frac{8\times-1}{-15\times-1}=\frac{-8}{15}\)
