What is the difference between rational numbers and fractional numbers?

A fraction is a ratio of two numbers. Fractions are typically ratios of integers (where the denominator is not zero), which makes them "rational." The root word of rational is ratio.
You could have pi/2, or sqr(2)/2, both of which are fractions that are NOT rational.

The set of rational numbers is the union of the set of fractional numbers and the set of whole numbers.
What is the difference between rational exponents and integer exponents?
"Integer" means whole numbers, such as 5, 3, or -2; "rational" means fractional numbers (with whole numbers for the numerator and denominator), such as 1/2, -2/3, etc. This also includes whole numbers.
