Is 0.2 with a horizontal line over it greater than 0.2 without the line?

Answer 1

Yes, the bar over the 2, means that the digit (or digits) are repeated forever.

so 0.2 (with bar over 2) = 0.2222222222..... is decimal for 2/9 (fraction)

and 0.2 (no bar) = 0.200000000 which is 2/10

you could look at it a few ways.

0.2222222.... = 0.2 + 0.0222222.... which is greater than 0.2

or compare 2/9 & 2/10, 2/9 = 20/90 & 2/10 = 18/90

with the same denominator 20 > 18, so 2/9 > 2/10

Answer 2

Yes, it is greater by 0.022222222222.

Answer 3

in fraction 2/9

Answer 4

Yes. 0.2 with a vinculum(the bar) is equal to 0.2222222..., while without it, it is just 0.2 .
