What property of multiplication do we use to rename fractions?

To rename fractions, we use the property of multiplication known as the "multiplicative identity" or "multiplying by one." This property allows us to multiply the numerator and denominator of a fraction by the same non-zero number, effectively creating an equivalent fraction. For example, multiplying both parts of the fraction ( \frac{1}{2} ) by 3 gives ( \frac{3}{6} ), which is an equivalent fraction. This process maintains the value of the fraction while changing its appearance.
