What you’ll learn

  1. Top and BottomName the numerator and denominator and explain what each tells you.A fraction has a numerator on top and a denominator on the bottom. The denominator says how many equal parts the whole is split into; the numerator says how many of those parts you have.
  2. Kinds of FractionsClassify fractions as unit, proper, improper, mixed, or equivalent.A unit fraction has 1 on top (1/5). A proper fraction is less than one whole (3/4). An improper fraction is one or more (5/4), and can be written as a mixed number (1 1/4). Equivalent fractions name the same amount (1/2 = 2/4).
