A rational number is any number that satisfies the following three criteria: Any number divided by zero (i.e., where the denominator is zero) approaches infinity (or negative infinity), but is undefined. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. That's because while there is a restriction on the denominator (the "bottom" number in a fraction), there is no similar restriction on the numerator (the "top" number in a fraction). Lesson 10. However, the true number actually has the "6" repeating into infinity. Consequently, the rational number 6/4 is also equal to 3/2, because 6/4 can be simplified to 3/2.
