What is the correct way to write a number like 0.33333333...?

Question

When a number keeps repeating the same digit like 0.33333333 or 1.66666666 but I don't want to use a fraction to write it, is there a symbol that means that that digit keeps repeating? like a line over them or something? I think there is but I cant remember what it is.

Answer 1

Repeating decimal notation --> http://mathworld.wolfram.com/RepeatingDecimal.html

Answer 2

Yes, you are correct. You would write 0.3 with a straight line over the top of the three. The line over the 3 would mean it is repeating infinitely.

1.3 Like this, for lack of better symbols on my computer. Except the bar/line seems to show up over the number 1, but you get my drift I think.

Answer 3

Your memory is serving you well: placing a line over the repeating digit is the correct way to designate the repetition. You can also use this symbol for repeating sequences, such as 1/7th: 0.142857142857..., whereby you would place the bar over the six repeating digits.

Answer 4

What you're supposed to do is draw a line above the number that keeps repeating, so it shows repetition. I can't really show you on the computer, but it's like a dash above the number. Like you'd write 0.3 and put the line over the 3.

Answer 5

Yes your memory is better than you think... It is a line over the repeating part of the number:

.333333 =
**_
.33 Ignore the '*' yahoo deletes leading spaces...The line should be centered on the 3... but it is hard to do in type.

Note you might also have a number like 23.7452323232323... The the line is only over the repeating part:

********__
23.74523

Answer 6

0.3 with a dot over the 3. That means the 3 constantly repeats.
0.678 with a dot over the 6 and 8 means 678 constantly repeats.

DON'T listen to the other people this is the correct and modern way of doing it.

If you want to pronounce it say naught point three recurring.

Answer 7

A line over the last digit to the right. But, the fraction would take up less space.

Answer 8

The symbol is called a "recurring" symbol.You simply put a bar on the last digit. It amplies that digit repeats itself infinitely. Suppose you have two digits or three digits repeating themselves infinitely. Then you put the bar on all two or three digits. I can not draw and show you on this computer since there is no provision for it on computer.

Answer 9

With a line on top of the repeating digits...

Answer 10

i learned that the correct way to write a number like 0.333333333 is to write 0.33 with a line above the second three. it symbolizes a repeating decimal.

Answer 11

You would write .33 and put a line over the second three.
