Question

12.222222 (bar on 2) express as p/q

Answer 1

let x = 12.2222...------(1)

(multiple both sides by 10)

10x = 122.222....-------(2)

subtract 1 from 2

=> 10x-x = 122-12

9x=110

x =110/9

and the ans is 110/9

Answer 2

Answer:

Step-by-step explanation:

x = 12.2222222.........  ______________ eqn 1

10x = 122.222222........         (multiplying both sides by 10 ) ________     eqn2

now subtracting equation 2 by 1 we get ,

10x = 122.22222222.......

-   x = 12.22222222......

⇒ 9x = 11

⇒ x = 11/9

∴x= 11/9
