Is 0.313131 a rational number?
Yes, it is a repeating decimal. Terminating and repeating decimals are rationals. Rational numbers can also be expressed as a fraction. 0.313131 is a repeating decimal.
What is a decimal number that ends or recurs?
Decimal numbers that end or recur are known as terminating or repeating decimals. 0.75 is a terminating decimal. 0.4444 repeating is a repeating decimal.
Are all terminating and repeating decimals rational numbers and why?
Yes, they are and that is because any terminating or repeating decimal can be expressed in the form of a ratio, p/q where p and q are integers and q is non-zero.
Is a repeating or terminating decimal bigger?
Repeating decimal. * * * * * It depends on the numbers! For example, 0.6 < 0.66... < 0.67 By the first inequality the repeatiing decimal is bigger, by the second the terminating one is bigger.
What are two characteristics of a rational and irrational number?
Rational numbers - can be expressed as a fraction, and can be terminating and repeating decimals. Irrational numbers - can't be turned into fractions, and are non-repeating and non-terminating. (like pi)

What can rational numbers be expressed as?
fractions or decimals
What are the irrational numbers?
Irrational numbers are numbers that cannot be expressed as a ratio of two integers or as a repeating or terminating decimal.

What is the vocabulary for a terminating decimal and a repeating decimal?
They are both rational numbers.
Are all terminating and repeating decimals rational numbers and why?
Yes, they are and that is because any terminating or repeating decimal can be expressed in the form of a ratio, p/q where p and q are integers and q is non-zero.
What is a counterexample to show that the repeating decimals are closed under subtraction false?
In fact, the statement is true. Consequently, there is not a proper counterexample. The fallacy is in asserting that a terminating decimal is not a repeating decimal. First, there is the trivial argument that any terminating decimal can be written with a repeating string of trailing zeros. But, Cantor or Dedekind (I can't remember which) proved that any terminating decimal can also be expressed as a repeating decimal. For example, 2.35 can be written as 2.3499... Or 150,000 as 149,999.99... Thus, a terminating decimal becomes a recurring decimal. As a consequence, all real numbers can be expressed as infinite decimals. And that proves closure under addition.
Are all terminating and repeating decimal rational numbers?
Yes.
