The d e n o m i n a t o r is the
n u m b e r b e l o w t h e bar in a
fraction. It tells the n u m b e r of
e q u a l parts in o n e w h o l e .
The n u m e r a t o r is t h e n u m b e r
above t h e bar in a fraction. It
b)
tells t h e n u m b e r of e q u a l parts
the fraction
represents.
c)
This picture has 4 e q u a l parts,
so the d e n o m i n a t o r is 4.
Only 1 part is s h a d e d , so t h e
n u m e r a t o r is 1.
