Answer 2

let consider x = 0.999..... (I)

Multiply 10 into eqn (I) 0.999*10 = 9.999

Also multiply by 10 in X ( X * 10 = 10x)

let's consider 10x = 9.999 (ii) eqn

Now divide eqn (I) from (ii)

that is 10x - X and 9.999 - 0.999

9x = 9

value of X is 1 and you also write 1/1

With this pattern you can find the answer of all questions
