Plz slove this in your book step by step and send a photo/attachment

I'll mark has brainliest if answer correct...​​

Answer 1

Answer:

No

Step-by-step explanation:

Sorry. Can't take a photo but will explain briefly

Now, bring the numbers to a same form. Let's convert the mixed into improper fraction

$- 1 ( 1 / 8 ) = [ ( - 1 * 8 ) + 1 ] / 8 = ( - 8 + 1 ) / 8 = - 7 / 8$

Now , a multiplicative inverse set of numbers should get 1 in multiplication.

So, let's check it!

$- 7 / 8 * 8 / 9\\\\-7 * 1 / 9\\\\- 7 / 9$                           ( Numerator 8 and denominator 8 gets cancelled )

The answer is not 1. So these two are not multiplicatively inverse

Answer 2

Hey friend here is your answer!!

-1 1/8= -9/8

8/9* (-9/8) = -1

therefore -9/8 is not a multiplicative inverse of 8/9 because product is -1

a * 1/a =1

then 1/a is multiplicative inverse of a

Hope this answer helps u..

Have a great day
