Ian's Percentage Growing Post

Question:1
What is a good definition of percent? you should use words, symbols, pictures, and numerical example in your definition?

Question:2
How are three fifth (3/5),3:2, 60%, and 0.6 all at the same?use picture to show your answer?
3/5, 60% and 0.6 are the same because 3/5 is 60% and 60% is the decimal of 0.6

And 3:2 and 3/5 are also the same because if you convert 3/5 to ratio the answer is 3:2

Question:3 Show 3 different ways to find 35% of 80.
1)80/100=0.8
o.8 x 35%=28

2)3.) 80/10=8
5%=4
10%=8
48 x 4-5=28

3)35/100=28/80
Question:4
Find a link to blogs that deal with percentages. Leave a comment behind and add the link with a review (What the post was talking about....yes you have to read the post and why others should read the post) Hint In the side bar there are links to other schools.

Question 5:
The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms Lowrey's class met their reading goal for the month. Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not.

Ms Stanzi maybe right or wrong it depend on Ms Stanzi's class because for example if some students can't read is less than 55% she is wrong but if the students who can read is more than 55% she is right.
(i'm just guessing)
Question 6:
Use a hundred grid (unit square) to illustrate the following questions. Once you have explained and illustrated what the question means solve it.
a) 16 is 40% of what number?
