rational expression

To reduce a fraction to its lowest terms divide the numerator and the denominator by their highest common factor

Long Answer: A rational number is a number that can be written as a fraction where both the numerator and denominator are both integers and the denominator does not equal 0. Since 8 and 5 are both integers, then this is a rational number. Short Answer: Rational

1) Factor both the denominator and numerator 2) State restrictions 3) Reduce fraction if possible 4) Find LCD 5) Multiply LCD into both numerator and denominator 6) Cross out the like terms 7) Add and Subtract 8) Simplify if possible

-- If the numerator and denominator of the fraction are both whole numbers,then the fraction is definitely a rational number.-- Even if they're not both whole numbers, it still canbe a rational number.-- Makes no difference whether the fraction is negative or positive, improper or proper.

Only if the square root of the numerator and the square root of the denominator are both rational numbers.

Absolutely. As long as it can be expressed as a fraction with the denominator not being zero, and both numerator and denominator being integers.

No. A number will have a rational square root, only if both the numerator and denominator of the simplified fraction are squares of integers.

Integers and fractions that have integers in the numerator and denominator are rational. A number can't be rational and irrational at the same time - irrational means "not rational".
