Yes, it is.

Yes.

It is bar 0.58585 :)

No. It's the ratio of 6,434,343 to 10,000,000 . Any number that you can write completely with digits, and a decimal point or a fraction bar if you need them, is a rational number.

-0.7777 repeating = -7/9

If there is a bar over a number it means that it is an irrational number or possibly an infinite number. A number with a bar over it cannot be considered a whole number.

Yes, it is.

Yes.

Bar notation is a decimal with a repeated number with a line on top of the repeated number. EX.) 4.23232323 would be 4.23 with a line over the 4.23. another... EX.) 5. 22222222222222 would be 5.22 with a line over the 5.22. Last one ... cut off after the second 7 put a line OVER the bolded 7 EX.) 7.907777777777 would be 7.9077 with a line over the 7.9077. that is bar notation :)

An irrational number is a number that cannot be expressed as a fraction. So whole numbers and fractions are out. You can then just make a number like 6.34298374923743333333. You put a bar over the 3 so it repeats, and the number cant be expressed as a fraction, makin git an irrational number.

2.01 the bar notation is overthe .01

It is 0.98 with a bar over the 98.

It is bar 0.58585 :)

No. Any number you can completely write down with digits, plus a fraction bar or a decimal point if you need one, is rational.

Sorry, but it is not possible to use a notation bar with this browser.
