The bar is only used for repeating decimals. If it is repeating, you can use it.

What is the bar notation of 0.7777?

The bar notation of 0.7777 is written as 0.7 with a bar over the digit 7, indicating that the digit 7 repeats infinitely.

In mathematical notation, this is equivalent to the fraction 7/9, as the repeating decimal 0.7777 can be expressed as 7 divided by 9.


Are repeating decimal irrational?

No.Repeating decimals are rational.To convert a repeating decimal to a fraction, put the repeating digit(s) over the same number of 9s and simplify:examples.0.333...It has one repeating digit (3) so put it over one 9 (9) to get 3/9 which can be simplified by dividing top and bottom by 3 (the hcf of 3 and 9) to get 1/3. Thus: 0.333... = 1/30.181818...It has two repeating digits (18) so put them over two 9s (99) to get 18/99 which can be simplified by dividing top and bottom by 9 (the hcf of 18 and 99) to get 2/11. Thus: 0.181818.... = 2/11


How do you put three seventh into decimal form?

To put 3/7 into decimal form, you would divide 3 by 7, which would be 0.428571... repeating those 6 digits forever; normally it would be approximated by being rounded to, say, 2 or 3 decimal places, that is 3/7 ≈ 0.43 or 0.429


How do you turn a whole mixed number into a decimal?

divide the numerator by the denominator, and round to the nearest tenth or hundredth, whatever is best. Ex. 1 1/2 = 1.5 since 1 divided by 2 is .5, make the new number 1.5. if the number is 1 1/3, then the decimal would be 1.33333..... so then you would round it to the nearest tenth (1.3) or the nearest hundredth (1.33) and then put a repeating bar over the decimal.
