Answer 1

I think u mean bar( on the top of the number otherwise underline doesn't mean anything.)
pls mark my answer as brainiest and follow me.

answer is 3178/9999

which is an rational number in the form of a/b where a and b are integers and b is not equals to 9. ; )

0.3178(bar)=x. (1)
3178.31783178.........=10000x. (2)

we have to subtract 1 from 2

10000x-x = 3178.31783178......-0.3178.......

=9999x=3178

x=3178/9999 (answer)

Answer 2
