Sorry this is late but lets get right down to the work.

Question 2

a)Explain how to show more then 100% using 100 squares.

b)Explain how to fill in less then 1% using 100 squares.

a)To fill in a percent more then 100 you simply us

e more then one square when filling it in.

eg: for 130% you would fill in 100 squares on one of the 100 squa

re sheets and then 30 of the 100 squares on a second square

b) To fill in a percent less the 100 you simply only fill a portion of 1 of the 100 possible squares.

6. Represent each percent on a grid

a) 125%

b) 10 1/2%

c) 0.4%

d) 262%

e) 7/8%

f) 45.6%

I scanned my answers for this one sorry there a little messy.

11. The land of Alberta is 113% the land of Saskatchewan. Show how the land area compares using hundred grids.

A simple grid can show the difference in land:

Saskatchewan Alberta

14. a) If 200 squares were used instead of 100 squares to represent 100%, how would you show 0.25%?

b) If 400 squares were used instead of 100 squares to represent 100%, how would you show 0.75%?

(My scanner stoped working after that last scan so i just took this picture from mytextbook.ca)

a) If we used 200 squares instead of 100 we would need to double the numerator because the denominator (100) was doubled so when representing what would normally appear as 1/4 would now appear as 1/2 but still be equal to 1/4.

b) If we used 400 squares instead of 100 we would need to quadruple the numerator because the denominator (100) was quadrupled so when representing what would normally appear as 3/4 would now appear as 3 but still be equal to 3/4.

And that was my (slightly late) scribepost I hope it was informative.
