Fraction - A fraction is a method of expressing a number that is not a whole number. It consists of two numbers, the top number, called a numerator, and the bottom number, called a denominator. It is written in the form ^a/_b.
A fraction is also a way to write a division problem, where the numerator is the quotient and the denominator is the divisor. All fractions are division problems and all division problems can be written as fractions.
