We can evaluate expression one by one,
1
[tex]\begin{gathered} \frac{2}{3}=\frac{6}{9} \\ \frac{6}{9}\rightarrow\frac{3\times2}{3\times3}=\frac{2}{3} \end{gathered}[/tex]This is true.
2.
[tex]\begin{gathered} \frac{4}{5}>\frac{8}{16} \\ \frac{8}{16}=\frac{1}{2}=0.5 \\ \frac{4}{5}=0.8 \\ \text{0}.8>0.5 \end{gathered}[/tex]This is true.
3.
[tex]\begin{gathered} \frac{2}{5}<\frac{5}{10} \\ \frac{5}{10}=\frac{5}{5\times2}=\frac{1}{2}=0.5 \\ \frac{2}{5}=0.4 \\ \text{0}.4<0.5 \end{gathered}[/tex]This is true.
4.
[tex]\begin{gathered} \frac{1}{2}>\frac{3}{4} \\ \frac{1}{2}=0.5 \\ \frac{3}{4}=0.75 \\ \end{gathered}[/tex]This is not true.
Thus, the correct option is D
