Answer 1

Answer: 1. Additive identity 0

Multiplicative identity 1

2. 19/6 and 2

.4. 1

5. 1 2 3 4

Step-by-step explanation:

Answer 2

Step-by-step explanation:

1. What are the multiplicative and additive identities of rational numbers?

Ans: Multiplicative identity is when a number is multiplied by something it is the same number so the multiplicative identity is 1 and additive identity also same thing so additive identity is 0 Eg: 1*3 = 3; 6+0 = 6

2. Write the additive inverse of 19/-6 and -⅔

Ans: additive inverse of 19/-6 is -19/6  (just reverse the signs)

        additive inverse of  -⅔ is 2/-3  (just reverse the signs)

3. Write the multiplicative inverse of -13/19 and -7

Ans: multiplicative inverse of -13/19 is 19/-13 (just reciprocal it)

        multiplicative inverse of -7 is 1/-7 (just reciprocal it)

4. Mention a rational number which has no reciprocal.

Ans: 0 has no reciprocal

5.  Mention any 4 rational numbers which are less than 5.

Ans: 4, 3, 2, 1 and 0 are less than 5
