Question

0.777777.......inp/q form

Answer 1

Let x = 0.7777...........    (i) equation.

  10x = 7.7777...........    (ii) equation.


By subtracting (i) equation from (ii) equation.


10x = 7.7777........
    x = 0.7777........
------------------------------
  9x = 7.0000..........
------------------------------


9x = 7

x = 7/9

so, 7/9 is the form of p/q.


You can also check the answer

7/9 = 7.7777.......

Answer 2

 Let 0.7777....be x
⇒x=0.7777......_________(Equation-1)

Multiplying both sides by 10 

⇒10x = 7.7777.....________ (Equation-2)

By subtracting equation 1 from equation 2,we ge

10x = 7.7777........
    x = 0.7777........
------------------------------
  9x = 7
------------------------------

9x = 7

x = 7/9

So,Answer will be x=7/9
and!!
7/9=0.77777777777.............
