•
•
A fraction is another representation for division.
Equivalent fractions represent the same value.
Whole numbers can be classified into subsets.
Divisibility rules can be used to find equivalent fractions quickly.
Fractions and decimals are different representations for the same amounts and
can be used interchangeably.
