To solve \( \frac{4}{6} - \frac{1}{2} \), you first need to have a common denominator.
The denominator of \( \frac{4}{6} \) is 6, and the denominator of \( \frac{1}{2} \) can be converted to 6 by multiplying both the numerator and the denominator by 3:
\[ \frac{1}{2} = \frac{1 \cdot 3}{2 \cdot 3} = \frac{3}{6} \]
Now the expression looks like this:
\[ \frac{4}{6} - \frac{3}{6} \]
Subtracting the fractions:
\[ \frac{4 - 3}{6} = \frac{1}{6} \]
So, \( \frac{4}{6} - \frac{1}{2} = \frac{1}{6} \).
