Please help me, I will mark your correct answer as smartest ps. Gain 30 points!!)

Answer 1

Her answer is wrong. You might spend an hour looking at her work....

but no! Her work is all right.

That line means those three digits are recurring - they repeat itself over and over. 

But the pattern is 0.5454545454545454545... and so on.

Her answer?

0.545545545545545545545545545... and so on.

"0.545545" 
     VS
"0.545454"

is different.

So the actual answer?

0.54, with the line on top of "54."

Answer 2

The line should be over the part that repeats
the real anser is 0.54545454
the part that repeats is 54
so it should be 0.54 with a line over it
by doing 0.545 witha line, that means 0.545545545545 which is wrong
