### Camille's Percentage Growing Post

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

CLICK THE PICTURE!

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

If you divide 3 into 5, you will get o.6 = 3/5=0.6

If you divide 3 into 5, then times it by 100, you will get 60% = 3/5 = 0.6 x 100 = 60%

3/5 and 3:2 are also the same. The number 3 (numerator) is the first part, then subtract the number 5 (demoninator) into number 3 (numerator) (5-3=2) so you can get the second part. So 3/5 becomes 3:5.

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

1.) 80/100=0.8 or 1%
0.8=1%
35 x 0.8=28 (35% of 80 is 28)

2.) 80/2=40 or 50%
50%=40
50/2=25%
25 = 20
40/2=20 or 25% + 10 = 8

25=20
+10=8
______
35 = 28
______
100 = 80

(25 x 0.8 = 20, 10 x 0.8=8, 35 x 0.8=28, 100 x 0.8=80)

3.) 80/10=8
5%=4 because half of 10 is 5 and 4 is half of 8.
10%=8
5%=4
8 x 4-5=28

Question #4:

I found a link to blogs that deals with percentages. I left a comment and I told the scriber that he or she did a really graet job (that's not all, I added more). Here's the link: http://linden8z.blogspot.com/

The scriber showed 3 different ways of how to get a percent. The scriber explained each 3 different ways.
1.)Other people should read the post because they can learn something that they don not know by reading the post.
2.)If they forgot how to do the 3 different ways, they can go to that blog and read the post.
3.)If they can't understand how to do it, they can go to that blog and read it.

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's could be correct. Why? What if Ms. Stanzi's class is greater than Ms. Lowrey's class. Example: Whta if Ms. Stanzi has 50 students. Divide 50 by 2, 50/2=25. And what if Ms. Lowrey has 40 students. Divide 40 by 2, 40/2=20. Ms. Stanzi=25 students meet their reading goal, Ms. Lowrey=20 students meet their reading goal. That's why Ms. Stanzi could be right if she have more students than Ms. Lowrey.

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?

b) What is 120% of 30?
You need 2 grids because 120 is larger than 100
