One model for fractions can be constructed
from a circle . We relate fractions to things that
are common because it makes them
easier to work with. For instance, consider a
pizza. The one at the left was cut into eight
pieces. What fraction of the pizza is missing? ________ What fraction
of the pizza remains? ________ If you add those two fractions together,
you should get the original size. That is, 1 eighth plus 7 eighths is 8
eighths or 1 whole. In numbers ,
S-O-L-V-E: Samantha ate
of a pizza. Alec ate
of the same pizza.
What fraction of the pizza was eaten?
What fraction of the pizza is left?
If there were eight pieces in the pizza to begin with, how
How many pieces are left if there were 16 pieces in the
