Question

Give a proper explanation of this question. Bit - (i) and (ii) both.​

Answer 1

It's Easy

Step-by-step explanation:

-(-x)=X

Substitute X with 11/15

-(-11/15)=11/15

-1((11/15)*(-1/-1))=11/15

-1*11/-15=11/15 i.e.,

-1*11/-1*15=11/15

-1 & -1 gets cancelled.

11/15=11/15.

Hence proved. Do the same method for 2nd bit
