When writing a repeating decimal as fraction why does the fraction always have only 9s as the denominator?

There can be no answer to the question because it is based on a false assumption.0.3333... repeating = 1/3 : I don't see any 9s in the denominator!
or 0.0111... repeating = 11/990 : I would not consider the last digit in the denominator to be 9.
Having said that, the significance of 9 is that we count in blocks of one more: 10s.

Writing fractions as a decimal?
CONVERTING DECIMAL TO FRACTION Example: 1. Make 12.2 into a whole number. In this case, multiply 12.2 by 10. 2. Whatever is multiplied to 12.2 should also be divided to it so as not to change the value of 12.2. Therefore: 12.2 * 10/10 = 122/10 or 61/5 in fraction in lowest term
Writing mixed numbers as decimal. Rounded to the nearest hundredth?
This is a few problems. To convert a mixed number to an improper fraction, multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator. To convert an improper fraction to a decimal, divide the denominator into the numerator. To round a number to a particular digit, look at the digit immediately to the right of your target, in this case, the thousandths place. If that digit is 4 or lower, zero it and everything to the right of it out. If that digit is 5 or higher, increase the target digit by one and zero everything to the right of it out. If your target digit is a 9, increasing it will turn it to zero and increase the digit to the left of it by one.
How do you change 533 to fraction or mixed number as a decimal?
533 is an integer and so there is no sensible way of writing it as a fraction or mixed number.A decimal number is simply a way of representing a number in such a way that the place value of a one is ten times that of a one in the place to its right. If it does not contain a fractional part then the decimal representation does not require a decimal point. So the decimal for 533 is 533 – as in the question.

Can 8.63 be made into a fraction if so what is the fraction?
Every number with a finite number of digits can be made into a fraction. Start by writing your decimal number in the numerator, divided by 1 in the denominator (since dividing by 1 doesn't change the value of any number). Then, each time you move the decimal place to the right, add one "0" to the denominator. In this case, since there are two decimal places, we add two zeros, and the fraction is 863/100.

When writing a reoccurring (repeating) decimal it is usually expressed as one decimal with a line over the top of it.
How do you write 0.44 in fraction?
To write 0.44 as a fraction, we can start by writing the number without the decimal point as 44. Since there are two decimal places in 0.44, we can write 44/100 as the fraction. However, we can simplify this fraction by dividing both the numerator and denominator by their greatest common factor of 4, resulting in 11/25.

What is 6 over 35 as a decimal?
0.1714285714285714285714 etc.. And although it does turn out to be like that, the proper way to right it without repeating is .....________ 0.1714285 Note: Please ignore the dots in front of the line. And the line is to be writing above the number starting with the 7, indicating that that's what repeats. Also keep in mind that just because that it's a repeating decimal doesn't mean it's irrational. It's written as a fraction. Any fraction is rational, so this repeating decimal is rational.
