The question is: is there any other irrational number that the result of (1 to n-1)/n results in a series of n-1 repeating numbers in the exact same order for every possible fraction?

∙ 12y agoThe question only shows ten places of decimals, then it stops. In the form given in the question it is not a recurring decimal. A recurring decimal continues infinitely. e.g. 1/3 rd expressed as a decimal has an answer of infinite length. Of course, if the question only shows part of the decimal value, and if that value actually extends infinitely, then it is a recurring decimal. Other examples of recurring decimals: 1/7, 1/13, etc. For more comprehensive information about recurring decimals, see 'Related Links' below the following advertisements.

You can only round a number to 2 decimal places if it currently has more than 2 decimal places.

Expressed as a decimal, 5/12 is equal to 0.416 recurring (that is, 0.416666...)Assuming you mean the fraction 5/12, you would take the top number and divide by the bottom number. The line in a fraction really means "of" or "divided by."5/12 = 0.4166667That is only approximate since that is a repeating decimal.

that would be 0.33 but it depends on the amount of decimal places you are using, the decimal of one third is infinite; never ends. for example 5 decimal places would be -> 0.33333The decimal form of one third is the decimal .3 repeating,so .333333.......1 third = 0.33333.... [repeating 3] To signal that this is recurring there is a dot on top of the last three. This signals that the decimal is recurring and goes on forever. Usually people only write the first three places in a recurring decimal due to that it goes on forever.1/3 is sorta messy as a decimal, as it translates into 0.33333 - and the threes just keep coming for as many as you care to use.
If the prime factorisation of the fraction's denominator consists only of the primes 2 and/or 5 it will be a non-recurring decimal; otherwise it will.
A decimal need not be a rational. A non-terminating, non recurring decimal is an irrational number. Only a terminating decimal or a recurring decimal is rational and that is because such a number can be expressed as a ratio of two integers.
Not all decimals can be expressed as fractions. Only terminating and recurring decimals can be expressed as fractions. eg a recurring decimal: 0.3333333... = 1/3 A terminating decimal: 0.125 = 1/8 A decimal that does not recurr or terminate, cannot be expressed as a fraction. eg Pi = 3.141592654... Pi can not be expressed as a fraction as it does not recurr or terminate. It can only be approximated to a fraction. eg Pi ≈ 355/113 but is correct to 6 decimal places.

It is easier for people with a basic level of mathematical skills to understand decimal numbers with only a few digits after the decimal point. Besides, few labels refer to things which are packaged with an accuracy of more than 2 places after the decimal point.

No. Only rational numbers have a recurring decimal; √2 is irrational.
12.782 has three decimal places while 12.78 has two decimal places only.
