\(\frac{1}{3}\) = \(\frac{1 \times 2}{3 \times 2}\) = \(\frac{2}{6}\)
\(\frac{2}{3}\) = \(\frac{2 \times 2}{3 \times 2}\) = \(\frac{4}{6}\)
So an appropriate fraction is \(\frac{3}{6}\) = \(\frac{3 :3}{6 : 3}\) = \(\frac{1}{2}\)
\(\frac{1}{3}\) = \(\frac{1 \times 2}{3 \times 2}\) = \(\frac{2}{6}\)
\(\frac{2}{3}\) = \(\frac{2 \times 2}{3 \times 2}\) = \(\frac{4}{6}\)
So an appropriate fraction is \(\frac{3}{6}\) = \(\frac{3 :3}{6 : 3}\) = \(\frac{1}{2}\)
