Question

One ($1$) is -

• A. the identity for addition of rational numbers
• B. the identity for subtraction of rational numbers.
• C. the identity for multiplication of rational numbers.
• D. the identity for division of rational numbers.

Answer 1

The correct option is C

the identity for multiplication of rational numbers.

We know that whenever we multiply any number with$1$we get the same result, which means it does not change the identity of the number with which it is multiplied.

That's why,$1$is known as the multiplicative identity.

Ex. $5\times 1=5,-10\times 1=-10,\frac{2}{5}\times 1=\frac{2}{5},.......etc$

Hence, the correct answer is “ the identity for multiplication of rational numbers.”
