equally partitioned; explain that a numerator greater than one indicates the number of unit pieces represented by
the fraction.

 Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts
For example: Unit fractions are fractions with a numerator of 1 derived from a whole partitioned into equal parts and having 1 of those equal parts (1/4 is 1 part of 4 equal parts). Understand a fraction a/b as the quantity formed by a parts of size 1/b
For example: Unit fractions can be joined together to make nonunit fractions (1/4 + 1/4 + 1/4 = 3/4).
