### Identifying Numerator, Denominator, and Unit

Every fractional measurement needs to contain three pieces of information:
• The denominator tells me the name of the parts being used.
• The numerator tells me how many of those pieces are filled.
• The unit is whatever was broken up to make those pieces.
So, for example, if I say "three fourths of a cup," then I have three pieces, where each is a fourth part made from a cup. So, "three" is the numerator, "fourths" is the denominator, and "cup" is the unit.
