The prime factor of 9=3×3. As 3 is a number which cannot divide 10 hence in decimal system of numbering if a number is divided by 9 it results in an repeating fraction. As to why it is REPEATING it is because 9 can have only a finite number of unique remainders which range from 0–8.
What fractions are repeating?
A fraction in lowest terms with a prime denominator other than 2 or 5 (i.e. coprime to 10) always produces a repeating decimal. The length of the repetend (period of the repeating decimal segment) of 1p is equal to the order of 10 modulo p.
What type of number is 0.25726 repeating?
Any decimal number that terminates is a rational number. For example, 3.785=37851000. It turns out that any decimal number that repeats is also a rational number.

Is 3/7 terminating or repeating?
(You may want to check the form your instructor likes). 37 expressed as a decimal fraction is a repeating decimal with a fairly long (7 digit) pattern before repeating (you can verify this by long division.
Which is larger the numerator or the fraction?
Proper Fractions: The numerator is always smaller than the denominator. For example, 3/8 and 7/9. Improper fractions: The numerator is always larger than the denominator. Example, 9/2 and 7/5.
Is the denominator 2 an integer or a rational number?
Denominator 2 is also an integer and not equal to zero (0). So, we can say that yes, 2½ = 3/2 is a rational number. Example 3: Consider a number 12/-32. Now, let’s see whether it is a fraction or rational number.
Why do we rationalize the denominator in math?
// We’ll go over a few reasons why it might be a good idea: 1:34 It’s easier for teachers to grade work when everyone’s giving their answers in the same format. 1:51 Historically, we think about rationalized fractions as being reduced to lower terms, compared with non-rationalized fractions.
Can a fraction be written as a rational number?
It can also be expressed as a ratio of integers, i.e., can be written as a fraction of two integers with the upper number as numerator and bottom as the non-zero denominator. Since the denominator can be equal to 1, all integers are rational numbers. Moreover, several floating-point numbers can be expressed as fractions.
