Question

What are the multiplicative and additive identities of rational numbers?

Answer 1

Answer:

in additive inverse we have to just change the signs for eg

=2/5 = -2/5

Only the signs are changed

But in multiplicative inverse we have to reciprocate the given numbers for eg

=75/56 so it will be equal to 56/75

Hope u understand ans plz mark me branilst

Answer 2

$answer :$

★ADDITIVE INVERSE :

In this case the power notation of the numbers gets changed. Here, the positive ones turn to negative and the negative ones turn out to be positive.

example :

2/3 ➡ -2/3 ( additive inverse)

★MULTIPLICATIVE INVERSE :

Multiplicative inverse is just an other abbreviation of reciprocal where the numerator and denominator gets exchange but the sign remains fixed at it's position.

example :

1) 2/3 ➡ 3/2 (multiplicative inverse)

2) -15/8 ➡ -8/15 (multiplicative inverse)

Hope it helps u having a clear concept ❤
