In
2001, 7 million digital cameras were sold in the United States. The following year, 23 million
digital cameras were sold. About how many more digital cameras were sold each day in
2002?
Order the
steps to find the answer.
a.  There are 365
days in a year. Divide 16 million by 365 to calculate how many more digital cameras were sold each
day in 2002.  b.  The difference is 16 million.  c.  Write both
values on a place value chart.  d.  About 44 000 more digital cameras were sold each day in
2002.  e.  Use a calculator to divide 16 000 000 by 365. The answer
is about 44 000.   



James is an immigrant from Australia. He wonders how much
more the population increases each day in Canada than in Australia.
Order the steps James takes to find the
answer.
a.  He used a calculator to calculate the daily population increase
in Canada and Australia more easily. 1 000 000 ÷ 1095 = 913, or
about 1000, and 400 000 ÷ 1095 = 365, or about 400.  b.  In Canada, the
daily population increases about 1000, while in Australia the daily population increases about 400.
Canada adds about 600 more people per day to its population than Australia.  c.  There are 365
days in a year. 365 x 3 years = 1095.  d.  He wrote both values on a value
chart.  e.  On the Internet, he found that the population of Canada grew by
about 1 million people from 2002 to 2005. The population of Australia grew by 400 000 people from
2002 to 2005.
