To find out how many sixths are in \( \frac{2}{3} \), we can divide \( \frac{2}{3} \) by \( \frac{1}{6} \):
\[ \frac{2}{3} \div \frac{1}{6} = \frac{2}{3} \times \frac{6}{1} \]
Now multiply the fractions:
\[ = \frac{2 \times 6}{3 \times 1} = \frac{12}{3} = 4 \]
So, there are 4 sixths in \( \frac{2}{3} \).
