If it is a repeating decimal for a rational number, such as 1/3 (.333...), you can write the sequence once and draw a "repeating" notation above the sequence. So in the case of 1/3, I would write ".3" with a horizontal line above the "3".
In the case of an irrational number such as Pi or a decimal for which you do not know the sequence repeated, you can just round it off to the precision required. For Pi, this is often expressed as "3.14," for example.
0.09 and it goes on like that forever.
periodic line
Irrational.
A recurring decimal (caused by the denominator of a fraction have a prime factor other than 2 and 5) or an irrational number (such as √2) goes on forever.
A terminating decimal is a decimal number whose digits don't go on forever, like 3.45. A non-terminating decimal is a decimal number that goes on forever, like 1/3 = 0.3333333... since the 3's go on forever. So any repeating decimal is non-terminating. Also, numbers like pi go on forever: 3.1415926535897932384626.......
0.66 itself doesn't go on forever. If you are trying to express two thirds as a decimal, then it is 0.66 recurring. So that will go on forever.

It goes on forever in a non-repeating fashion.
Answer: 0.6 (goes on forever)
Irrational.
.888888888888888 it goes on forever and never ends.

7 over 6 as a decimal is 1.166666.... (6 goes on forever). Hope that helps :)
The number goes on forever and the decimal value is random.
A terminating decimal is a decimal number whose digits don't go on forever, like 3.45. A non-terminating decimal is a decimal number that goes on forever, like 1/3 = 0.3333333... since the 3's go on forever. So any repeating decimal is non-terminating.
