Respuesta :

The answer is B:  1/2 x 1 = 1/2

Answer:

(B)

Step-by-step explanation:

A multiplicative identity is the property in which when a number is multiplied with one (1), the number remains unchanged.

Thus, (A) The given sentence is :

[tex]\frac{1}{2}{\times}2=1[/tex]

This sentence does no undergo multiplication with 1, therefore, this option does not demonstrates the multiplicative property, hence this option is incorrect.

(B) The given sentence is:

[tex]\frac{1}{2}{\times}1=\frac{1}{2}[/tex]

This sentence undergoes multiplication with 1 and gives the unchanged number, thus this option demonstrates the multiplicative identity, hence this option is correct.

(C) The given sentence  is :

[tex]\frac{1}{2}+0=\frac{1}{2}[/tex]

The given expression undergoes addition, thus this option is incorrect.
