What do you call numbers which can only be written as a fraction?

>>8449103
Fractions can be written as decimals so I guess you mean the empty set.

[math]\mathbb{Q} \setminus \mathbb{Z}[/math]?

>>8449103
Rational numbers.
That's the word.

>>8449103
Not a valid set definition

He said "only" be written as a fraction.

Non-integer rationals.

Fractions

>>8449118
products of a bunch of different p-power roots of unity.

But I think he means [latex]\mathblackboard{Q}-\mathblackboard{Z}[\latex]

>>8449848
[math]\mathbb{Q} - \mathbb{Z}[/math]

L0Lno fgt pls
write [math] \frac{1}{17}[/math] as a decimal number

>>8450898
0.(0588235294117647)

fuck your period 16 repeating decimals

First of all, these numbers don't make any sense except if you restrict yourself to a base. 1/3 can be written with finite digits in base 12 for example.

Now in base 10, the numbers which are rationals and can be written without fractions, that is with finite digits, are simply written as n/ 10^m with (m,n) being integers.. So you take the set of these numbers and remove it from Q.
