HI there !!


x = 3.12222.....

10x = 31.2222... -----> (1)

100x =312.2222.... ------->(2)


Subtracting (1) from (2) ,

100x - 10x = 312.22 - 31.222

90 x = 281

x = 281/90

hope this helps u

Let x= 3.112bar-------(1)

On multiplication with
1000

1000x = 3112.222.--------(2)

On again multiplication with 10 to equation 2

10000x = 31122.222..---(3)

Subtracting eqn (3)-(2)

9000x =28010.00
BC
So x = 28010/9000 

= 937/300 ans
