Question

10. Find additive and multiplicative inverse of 5/13 and also write
additive and multiplicative identity of rational numbers.​

Answer 1

Answer:

Additive inverse= -5/13

Multiplicative inverse= 13/5

Additive identity=0

Multiplicative identity=1

Step-by-step explanation:

To find the Additive inverse change the sign of the given number. Example:- 5/13+(-5/13)=0. So the Additive inverse of 5/13 is - 5/13.

To find the multiplicative inverse of a number reciprocal the given number. Example:- 5/13*13/5 in this cross multiplication will be done and 5 will be crossed by 5 and 13 will be crossed by 13 and the answer is 1. So the multiplicative inverse of 5/13 is 13/5
