Solution

The correct option is B $1$
The product of $1$ and any rational number is the rational number itself because $1$ is the multiplicative identity for rational numbers.

Ex: $\frac{3}{2}$ when multiplied by $1$ gives $\frac{3}{2}$ itself, which is a rational number.

The product of ........... and any rational number is the rational number itself.

The correct option is B 1The product of 1 and any rational number is the rational number itself because 1 is the multiplicative identity for rational numbers.Ex: 32 when multiplied by 1 gives 32 itself, which is a rational number.

The correct option is B $1$
The product of $1$ and any rational number is the rational number itself because $1$ is the multiplicative identity for rational numbers.

Ex: $\frac{3}{2}$ when multiplied by $1$ gives $\frac{3}{2}$ itself, which is a rational number.
