How do you write a multiplication equation with a half as a factor?

To write a multiplication equation with a half as a factor, you can express it in the form ( a \times \frac{1}{2} = b ), where ( a ) is the other factor and ( b ) is the product. For example, if you want to multiply 4 by a half, you would write it as ( 4 \times \frac{1}{2} = 2 ). This equation shows that half of 4 equals 2.
