How would 5/9 be classified? 1. Rational and real? 2. Whole and integer? 3. Only real? Or 4. Only irrational

Elena-2011 [213]

A rational number is any number that can be written as a ratio or a fraction.

So 5/9 is a rational number. So basically that eliminates 2, 3, and 4.

And we are left with 1. as our answer choice which is Rational and real.
