John's percentage growing post

Question #1:
What is a good definition of percent? You should use words symbols, pictures and numerical examples in your definition.




Question #2:
How are three fifths (3/5), 3:2, 60% and 0.6 all the same? Use pictures and words to show you answer.

-if you divide 3 by 5 you will get o.6.
-if you multiply o.6 by 100 you will get 60%.
-to get 3:2 subtract 5 (denominator) to 3 (numerator) you will get 2 as a part.

3 divided by 5=0.6
0.6 multiply by 100=60%
5-3=2 3:2

Question #3
Show 3 different ways to find 35% of 80.

a. 80 divided by 100=0.8
35%x0.8=28
35%/100 = 28/80

b. 35% divided by 100=0.35
0.35x80=28

c.80 divided by 100=0.8
10x0.8= 8
25x0.8= +20

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. Three of them have done work on percentages!

I found this blog http://linden8m.blogspot.com/ and it's about percentages.
They have great explanations about percentages and good examples too...

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.

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?

16 divided by40=0.4

0.4 multiply by 100=40

40 divided by 100=0.4

40 multiply by o.4=16

16 is the number of 40%.

b.What is 120% of 30?

120 divided by 100=1.2

1.2 multiply by 30=36
