Jabu says: “A fish tank costs about R240. If the fish tank is part of
the sale, then the pet shop owner asks about R4 per fish. That’s a
bargain!”

2. Check if Jabu is correct about the price.

Jabu asked the pet shop owner to let him know what size the fish
are. She sent this pie chart:

estimated sizes of 60 fish

Key:
4 cm to 6 cm 7 cm to 9 cm 10 cm to 12 cm

3. What story does the pie chart tell about the sizes of the
60 goldfish? Write the information in your book.

4. Read each statement and say whether you agree or disagree.
Explain why.

(a) More than half of the fish are between 7 cm and 9 cm
long.

(b) About a third of the fish are between 4 cm and 6 cm
long.
(c) About a third of the fish are between 10 cm and 12 cm
long.

(d) The big fish (10 cm to 12 cm) are almost twice as many
as the medium fish (7 cm to 9 cm).
