Answer: We have to write two fractions that are equivalent to 1(a) and 1(b):
1(a) Equivalent fraction to 1(b):
[tex]\begin{gathered} (a)\Rightarrow\frac{1}{3}=\frac{1}{3}\times\frac{2}{2}=\frac{2}{6} \\ \text{ Equivalent fraction is:} \\ \frac{2}{6}\Rightarrow1(b) \end{gathered}[/tex]Conclusion: The two fractions are Indeed the Equivalent!
