periodic line
If there is a line over a decimal, it means the decimal is repetitive. If you are typing it would look like this... .7
Either, the decimal with a line over what's repeating (eg. 0.6 with a line over it), or decimal repeating (eg. "point six repeating").
If the threes go on indefinitely, then it is a repeating decimal, represented by a line over the repeated number, also .333...(going on forever) is equivalent to 1/3
If handwritten, draw a line over the repeated numbers.
The line over a repeating decimal is called the vinculum.
periodic line
It means repeat that decimal forever with it's last digit.

Either, the decimal with a line over what's repeating (eg. 0.6 with a line over it), or decimal repeating (eg. "point six repeating").
A line over the decimal part of a number indicates that there is a part that recurs infinitely many times. Such numbers are rational.

The line over the digits that repeat in a repeating decimal.
It is placed over one length of repeating decimal digits.
you move the decimal point 2 spaces to the right. and VOILA!
0.63636 as a repeating decimal is 0.63 with a line over the 6 and the 3 Hope this helps :))
