Question

express 3.423 bar in the form p / q where pandq are integer and q not equal to zero
​

Answer 1

let 3.423 bar be x

x = 3.423423423.....

multiply 1000 by both the sides

1000 × x = 3.423423...×1000

1000x = 3423.423423...

subtract the above two equations

1000x - x = 3423.423423... - 3.423423....

999x = 3420

x=3420/999

x=1140/333

x=380/111
