That's because all repeating decimals can be converted into fractions. Here is an example: 4.161616... Let's call this number "x". Multiply by 100 (use a "1" followed by two zeroes in this case, because the repetition period is two), and write:
100x = 416.161616...
x = 4.161616...
Subtract the two equations:
99x = 412
x = 412 / 99
So there you have it - the number was converted to a fraction made up of integers - which is exactly the definition of "rational number".

Yes, they are.
Are all terminating and repeating numbers rational numbers?
All decimals that terminate, or end with a repeating set of digits are rational numbers. eg 1.234, 1.222..., 1.232323..., 1.23444..., 1.2343434... are all rational numbers.

Why can't repeating decimals be a rational number?
If the decimal representation of a number repeats, it isa rational number.
Are all nonterminating decimals irrational numbers?
Not at all. 0.33333... nonterminating = 1/3 rational 0.66666... nonterminating = 2/3 rational 0.1428571428... nonterminating = 1/7 rational 0.55555... nonterminating = 5/9 rational
What are the 3 types of rational numbers?
If you convert them into decimal form you can say there are terminating decimals, there are the integers, and there are repeating decimals. EX: 2.4 is a terminating decimal. 2.44444444... is a repeating decimal. 2 is an integer. all are rational numbers.
Is 39.81 repeating rational?
Yes it is. Repeating decimals are all repeating rationals.
Is 1 9 a rational number?
yes, all numbers except numbers that have non-terminating, non-repeating decimals.
