It is most correct to place the bar over the first set of repeating numbers. Some people teach a style that is also correct, showing one set of the repeated digits and then a second set with a bar over all the repeated digits.
This is not possible to show in this text-only format.
1/3 = 0.3 with a bar over the 3,
or 1/3 = 0.33 with a bar over the last 3.
1/7 = 0.142857 with a bar over all six digits, or
1/7 = 0.142857142857 with a bar over the last 6 digits.
Either format means the exact same thing. Your teacher may strongly prefer one or the other, or tell you to show your answer to at least 3 digits, or similar.
It is placed over one length of repeating decimal digits.
5.126 with a bar over the 126
For a single repeating digit, it is a dot over the digit.For string of repeating digits, it can be a dot over the first and last repeating digits, or a bar over the repeating string.
Answer = .3 with a bar above the 3 or .3 (3 repeating) or even ~.333 (if precision isn't very important). Note: Whenever you have a number in % or "percent" that you want to convert to a decimal number, simply divide the % number by 100 (for example: 33.3 % / 100 = .333). IF the % number is known to be repeating (for example 1/3=.3 repeating=33.3% (repeating)), then you can express the percent number in decimal as .3 with a bar above the 3 or as .3 (repeating) or even ~.333 (where "~" means "approximately). All are valid expressions of 33.3 % (repeating).
Well, honey, 22.2 with a bar over the 2 means it's repeating infinitely. So, technically it's 22.222222... forever. Just like that ex who won't stop blowing up your phone.
The bar is only used for repeating decimals. If it is repeating, you can use it.
place the bar over the first set of repeating numbers. for example, 1.345673456734567... would be written as 1.34567 with a bar over the "34567".
The bar is placed over the last full set of repeating digits shown.For example, with 2.783434... you would place a bar over the last 34But the number can also be written as 2.7834343... in which case the bar would be placed over the last 43.
decimal and repeating bar
A repeating decimal is usually shown with a bar over the decimal that is repeated
A bar.
It is placed over one length of repeating decimal digits.
The term I learned was "vinculum." The same term (and symbol) has other meanings in mathematics as well; as far as I know there isn't a specific term that ONLY means the bar used to indicate a repeating decimal.
Unless you wish to write 0.15000 and place the repeating bar over the last zero, there is no other decimal for 0.15.
With two thirds, you can put the bar anywhere, as long as its after the decimal point, of course. It would be simpler to put it over the 6 in the tenths place.
It is: 5.'63' repeating '63'
