10/23 = 0.bar(4347826086956521739130)

Explanation:

To find the exact decimal representation long divide 10 by 23 until the remainder repeats since:

20/46 = (color(red)(cancel(color(black)(2))) * 10) / (color(red)(cancel(color(black)(2))) * 23) = 10/23

Once the remainder repeats, the quotient will too.

So we find:

20/46 = 10/23 = 0.bar(4347826086956521739130)
