$\frac12 \cdot 3$
Correct Answer
$\frac32$
Explanation
We will begin by writing the integer 3 as a fraction. Then we can use the rule for multiplying two fractions to find the product.
- Write 3 as a fraction: 3 = \(\frac31\)
- \(\frac12 \cdot 3 = \frac12 \cdot \frac31\)
- Multiply the numerators. Multiply the denominators
- = \(\frac{1 \cdot 3}{2 \cdot 1}\)
- Since 3 and 2 have no common factors other than 1, the result is in simplest form
- = \(\frac32\)
