Pie Charts
A pie chart is a circle graph divided into pieces, each displaying the size of some related
piece of information. Pie charts are used to display the sizes of parts that make up some
whole.
Example 1:
The pie chart below shows the ingredients used to make a sausage and mushroom pizza.
The fraction of each ingredient by weight is shown in the pie chart below. We see that
half of the pizza's weight comes from the crust. The mushrooms make up the smallest
amount of the pizza by weight, since the slice corresponding to the mushrooms is
smallest. Note that the sum of the decimal sizes of each slice is equal to 1 (the "whole"
pizza").

YOU TRY!
Survey the people in your family or your friends about what type of toppings they like
on their pizza. Use the information you collect to create a pie chart that shows the
amount of people that like the different toppings people mentioned.
Example 2:
The pie chart below shows the ingredients used to make a sausage and mushroom pizza
weighing 1.6 kg. This is the same chart as above, except that the labels no longer tell the
fraction of the pizza made up by that ingredient, but the actual weight in kg of the
ingredient used. The sum of the numbers shown now equals 1.6 kg, the weight of the
pizza. The size of each slice is still the same, and shows us the fraction of the pizza made
up from that ingredient. To get the fraction of the pizza made up by any ingredient, divide
the weight of the ingredient by the weight of the pizza. What fraction of the pizza does
the sausage make up? We divide 0.12 kg by 1.6 kg, to get 0.075. This is the same value
as in the pie chart in the previous example.

Example 3:
The pie chart below shows the ingredients used to make a sausage and mushroom pizza.
The fraction of each ingredient by weight shown in the pie chart below is now given as a
percent. Again, we see that half of the pizza's weight, 50%, comes from the crust. Note
that the sum of the percent sizes of each slice is equal to 100%. Graphically, the same
information is given, but the data labels are different. Always be aware of how any chart
or graph is labeled.
Example 4:
The pie chart below shows the fractions of dogs in a dog competition in seven different
groups of dog breeds. We can see from the chart that 4 times as many dogs competed in
the sporting group as in the herding group. We can also see that the two most popular
groups of dogs accounted for almost half of the dogs in the competition. Suppose 1000
dogs entered the competition in all. We could figure the number of dogs in any group by

multiplying the fraction of dogs in any group by 1000. In the toy group, for example,
there were 0.12 × 1000 = 120 dogs in the competition.
YOU TRY!
Create a pie chart about what types of dogs your friends or family members like. Assume
that you ask 1000 people and multiply the amount you have per breed by 1000 to create
fractions for the results.

The Paleolithic Age, also known as the Old Stone Age, is the period of human development
beginning with the first use of stone tools by hominids (approximately 2 million years ago) and
ending with the receding of glaciers at the end of the Pleistocene epoch (roughly 10,000 years
ago). The Paleolithic was followed by the Mesolithic Age and then the Neolithic Age. Paleolithic
people were hunter-gatherers who used stone blades, axes, and spears to hunt animals.
Archaeological excavation of Paleolithic sites reveals the development of art in cave paintings
and small carved figures in stone, wood, and bone. Notable Paleolithic sites include Altamira in
Spain and Lascaux in France.
Look at the picture and answer the questions that follow.
Painting of bulls, horses, and stags at Lascaux Cave
IMAGE
[Corel]
Painting of a group of bulls, horses, and stags at Lascaux Cave. The cave, near present-day
Dordogne, France, was discovered by teenagers in 1940. It contains about 600 Paleolithic-era cave
paintings and 1,500 petroglyphs.
1. Describe the pictures drawn on the cave wall.
2. How did the artist try to show movement among the animals?
3. Why do you think the artist chose to draw these images instead of others?

Great Hall of Bulls at Lascaux
IMAGE
[Corel]
Section of Lascaux Cave (in present-day Dordogne, France) known as the Great Hall of Bulls. Lascaux
Cave, discovered in 1940, provides stunning examples of Paleolithic-era painting.
1.
Describe what you see in this cave painting.
2.
How is the size of the bulls different from that of the other animals in the picture?
3.
Why do you think the artist spent so much time drawing bulls rather than other animals?

1. What does this picture show you?
2. How do you know that the stag are swimming?
3. What might cause a herd of stag to get in the water and swim?

1.
What animals are in this picture?
2.
How is the bull drawn differently from the other animals?
3.
What does this picture say about the importance of the bull to the artist?
