Yes, they are.
The rational 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
All terminating decimal numbers are rational.
They can. And if you include repeating 0s and repeating 9s, then all rational numbers can be written with infinitely long repeating digits.
All repeating decimals are rational numbers. Not all rational numbers are repeating decimals.
Yes, they are.
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.
The rational numbers
If the decimal representation of a number repeats, it isa rational number.
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
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.
Yes it is. Repeating decimals are all repeating rationals.
yes, all numbers except numbers that have non-terminating, non-repeating decimals.
The set of rational numbers (ℚ).
Yes.
All terminating or repeating decimals are rational. -1.87652 terminates so it is rational.
