Help solving part 2 of consumer math homework!?

In early 2011, the U.S. Department of Housing and Urban Development reported some grim numbers on the housing industry. There were 503,000 building permits issued for single-family home construction in 2010, but that number was projected to decrease by 27.5% in 2011. Construction was expected to start on 378,000 new homes in 2011, which would have represented a 28.5% decrease from 2010. Also, in the 12-month period through January 2011, 281,000 new homes were sold, but this represented just 66.3% of new homes completed.

Part 1:

(a) How many fewer permits were expected to be issued for single-family homes in 2011

as compared to 2010? If necessary, round your answer to the nearest whole number.

It was projected that 138,325 fewer permits would be issued in 2011.

b. How many fewer new homes were started in 2011 compared to 2010? If necessary, round your answer to the nearest whole number.

There were 150,671 fewer new homes started in 2011

Part 2:

(c) How many new homes were completed in the 12-month period through January 2010, and how did that compare to the number of new homes started in 2011? If necessary, round your answer to the nearest whole number.

In the 12 month period through January 2011, there were 423,831 new homes completed, which was _________ fewer OR more than the number of new homes in 2010.

Update:

281,000=.663*x

which is 423,831

(x-378000)/(x)=.285

x=528,671

528,671-423,831=104,840 fewer homes

    I would graph these, and use actual numbers by calculating each figure. That way you can simply subtract to get each of the answers.
