Can a Fraction be Larger Than a Unit Whole?

If the red circle is the unit whole:

• Two pink pieces cover the red piece completely.
• Each pink piece is (one-half) of the red piece.
• The two pink pieces together are (two-halves). This shows that the red piece is divided into two equal parts and that both parts are covered.   means the same as one whole because the same area is covered.
• If we add one more pink, we have three-halves ( ) which is the same as one whole and one-half of another one, or 1 .
•  is called an improper fraction because the numerator is larger than the denominator.
• 1 is called a mixed number because it contains a whole number (1) and a fraction ( ).
