Simplify each fraction as follows:
[tex]\begin{gathered} \frac{4}{12}=\frac{4\times1}{4\times3}=\frac{1}{3} \\ \frac{2}{5}=\frac{2}{5} \\ \frac{3}{9}=\frac{3\times1}{3\times3}=\frac{1}{3} \\ \frac{1}{3}=\frac{1}{3} \end{gathered}[/tex]
As seen above, the three fractions 4/12,3/9 and 1/3 are equivalent.
The fraction 2/5 is not equivalent to the other three.
Hence 2/5 does not belong and is not equivalent to the other three given fractions.
