Question

Why is zero not the multiplicative identity of rational numbers?

Answer 1

Answer:

Step-by-step explanation:

Multiplication with zero gives zero. Multiplication with zero does not return the original number. That's why zero not the multiplicative identity of rational numbers.

Btw, zero is an additive identity because adding zero to a number returns the original number.

Answer 2

Answer:

Multiplicative identity means a number when multiplied with another number it gives the same number. For example, when we multiply 1 with 2 the product is 2. That's why 1 is known as the multiplicative identity. Zero is not the multiplicative identity because when it multiplies with another number, the product is zero.
