To find \( \frac{3}{4} \div \frac{1}{2} \), we multiply by the reciprocal of the second fraction:
\[ \frac{3}{4} \div \frac{1}{2} = \frac{3}{4} \times \frac{2}{1} \]
Now, multiply the fractions:
\[ \frac{3 \times 2}{4 \times 1} = \frac{6}{4} \]
Now simplify \( \frac{6}{4} \):
\[ \frac{6}{4} = \frac{3}{2} \]
This can also be expressed as \( 1 \frac{1}{2} \) or \( 1.5 \).
Therefore, the answer is \( 1 \) and \( \frac{1}{2} \).
