Answer 2

Answer:

Rational number - The numbers of the form p/q , where p and q are integers and q=/= 0 ,are called rational number.

1 is the rational number , whose multiplicative inverse is itself

let's understand

• We all know the multiplicative inverse of a/b = b/a

So,

1= 1/1

So multiplicative inverse of 1/1 is always 1/1 means 1

So, we can say the multiplicative inverse of. 1 is always 1 itself.

And 1 is rational number also.
