19. Find the sum of additive inverse and multiplicative inverse of 7.

20. Find the product of additive inverse and multiplicative inverse of -5.

​

Answer 1

Step-by-step explanation:

1. The additive inverse of 7 is –7..

Because,,, 7+(–7) = 0

multiplicative inverse of 7 is 1/7 ..

◾ Therefore,,, the sum of additive and multiplicative inverse of 7 is,,

= ( –7) + (1/7)

= –49 + 1 /7

= –48/7...

2. The product of –5 :-

= 5*(–1/5)

= 5
