Answer 1

Answer:

x = 7/9

Step-by-step explanation:

Let

                     x = 0.7777...                 (i)

then              10x=7.777...                (ii)

Subtracting (i) from (ii) we get -

                    9x =7

or,               x = 7/9

Answer 2

Answer:

7/9

Step-by-step explanation:

Let x = 0.77777.....

Multiplying 10 on both sides, we get

10x = 7.7777....

10x = 7+x (x = 0.777...)

10x - x = 7

9x = 7

x = 7/9
