What Is a Fraction?
A fraction represents a part of a whole or a division of one number by another, written as a numerator over a denominator, such as 3/4. The numerator shows how many parts are taken and the denominator how many equal parts make the whole. The denominator cannot be zero.
Simplifying
A fraction is in lowest terms when the numerator and denominator have no common factor other than 1; divide both by their greatest common factor. 18/24 = 3/4.
