No. 2 is a prime but 1/2 is not a repeating decimal.
Any fraction with a denominator which has a prime factorization that includes any prime other than 2 or 5, it can produce repeating decimals.If the prime factorization of the denominator does not include 2 nor 5 then the decimal representation will be a repeating decimal.
If the denominator has ANY prime factor other than 2 or 5, then the decimal is repeating.
It is a rational number which, in its simplest form, has a denominator with a prime factor other than 2 and 5.
Any rational number, whose denominator has a prime factor other than 2 or 5 will have a decimal representation which is repeating. The size of the number, in relation to 1, is irrelevant.
If a fraction, in its simplest form has a denominator whose only prime factors are 2 or 5, then the fraction is terminating. If the denominator has any other prime factor then the decimal is repeating.
If the denominator of the fraction has any prime factor other than 2 or 5, then it has a decimal representation with a repeating sequence of digits. If the denominator is a product of any number of 2s or 5s then it can be represented as a terminating decimal.
Any denominator which has a prime factor other than 2 or 5 will create a repeating decimal.
Any rational fraction such that, in its simplest form, the denominator contains a prime factor other than 2 and 5 will be a repeating decimal.
If the ratio, in its simplest form, has a denominator which has any prime factor other than 2 or 5, you will have a repeating decimal.
It is repeating. Any fraction in simplest terms which has ANY prime factor other than 2 or 5 in its denominator will be a repeating fraction.
If the denominator of the fraction, when written in its simplest form, has any prime factor other than 2 or 5 then it will be a repeating decimal fraction otherwise it will terminate.
If the denominator of the fraction, when written in its simplest form, has any prime factor other than 2 or 5 then it will be a repeating decimal fraction otherwise it will terminate.
