The fraction of the repeating decimal 0.7... is 7/9
It is a repeating decimal.
repeating decimal 1.1 as a fraction = 10/9
0.2 a repeating decimal into a fraction = 2/9
If it's a 6 repeating decimal then it is 224/3 if not then it is 746666/10000
If that is a terminating decimal, it is 2 535353/1000000 (as a mixed number) = 2535353/1000000 (as an improper fraction) If that is a repeating decimal 2.535353... with the 53 repeating, it is 2 53/99 = 251/99
You do a long division, adding decimal digits until you get a remainder of zero (terminating decimal) or a repeating pattern of decimal digits.
If the decimal is terminating or repeating then it can be written as a fraction. Decimal representations which are non-terminating and non-repeating cannot be expressed as a fraction.
A decimal number is like a mixed fraction: it has an integer part and a fractional part. If the fractional part is a repeating fraction then the whole number is represented by a repeating decimal.
an example of a repeating decimal is 0.33333333333333.......in this case the fraction is 1/3 another example is 0.66666666666 and the fraction is 2/3
2.3 repeating is already a decimal. It would look like this: 2.33333333333333... If you want a rounded decimal, you can use 2.3. However, 2.3 repeating would be more useful as a fraction for proportions and things. As a fraction, it is 2 1/3 (two and one third).
It is a fraction in decimal form.
