Until you become expert at this I suggest you do this in two stages (using c and d separately).
Suppose there are c digits after the decimal place where the digits are non-repeating, and followed by a repeating pattern of a string of d digits. Then the numerator is the old original string including one lot of the repeated digits minus the original string with none of the repeating digits. The denominator is 10^c*(10^d - 1), which is a string of d 9s followed by c 0s.
For example
123.26159159… There are 2 digits, "26", after the decimal point before the repeats kick in so c = 2, and the repeating string "159" is 3 digits long so d = 3.
So the numerator is 12326159 – 12326 = 12313833
and the denominator is 99900
Therefore the fraction is 12313833/99900.
decimal and repeating bar
It is a repeating decimal.
0.2 a repeating decimal into a fraction = 2/9
repeating decimal 1.1 as a fraction = 10/9
You do a long division, adding decimal digits until you get a remainder of zero (terminating decimal) or a repeating pattern of decimal digits.

The fraction of the repeating decimal 0.7... is 7/9
It is a repeating decimal.
0.2 a repeating decimal into a fraction = 2/9
repeating decimal 1.1 as a fraction = 10/9
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
If it's a 6 repeating decimal then it is 224/3 if not then it is 746666/10000
Oh, what a happy little question! When we see a repeating decimal like 1.142857, we can turn it into a fraction by noting that the repeating part is 142857. To convert this to a fraction, we put this repeating part over a series of nines equal to the number of repeating digits, which gives us 142857/999999. And just like that, we've turned our repeating decimal into a lovely fraction.

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).
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.
