Question

find product and additive immerse of 1/3

​

Answer 1

Additive inverse, −13

Multiplicative inverse, 3

Explanation:

For a number a, it's multiplicative inverse b is such that a⋅b=1 which is the multiplicative identity.

For a number a, it's additive inverse c would be such that a+c=0 where 0 is additive identity.

Thus, for a=13

It's additive inverse be c.

Then 13+c=0

Now, adding −13 to both sides,

c=−13.

Let the multiplicative inverse be b.

Then a⋅b=1

⇒13⋅b=1

Multiplying both sides with 3

b=3
