Math ? Can a fraction be irrational or are they all rational?

Question

explain?

Answer 1

a fraction whose numerator AND denominator are integers is rational

(denom not equal zero)

if a fraction can be "simplified" to having only integers in both

numerator and denominator, then it's rational

if not, it's irrational

Answer 2

Fractions are always rational.

Answer 3

A rational number is any number that can be expressed in the form:

a/b

where a and b are integers, and b is not equal to zero.

If both your numerator and denominator are integers, then the fraction must be rational (by definition)

Is it possible to have a fraction that looks like this:

(√10)/3 ?

Would this be rational or irrational ?

Answer 4

Why can't a fraction be irrational? Simple fractions of the form p/q, where p and q are integers and where q is not equal to 0 are rational.

But something like, root 2 / 2 or root 3 / root 7 + root 5 are obviously irrational.

I hope that helps. :)

Answer 5

An ir-ratio-nal number is one which cannot be expressed as the ratio of two integers. A fraction, such as 3/4 or 5/8, does precisely that. Therefore fractions are always rational numbers.

Answer 6

only the numbers are irrational, i've never heard of fraction irrational...:-??
