Aron 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 your answer.

If you divide these two numbers 3 and 5, the outcome will be o.6 = 3/5=0.6

Divide 3 into 5, then times it by 100, you should get 60% = 3/5 = 0.6 x 100 = 60%

3/5 and 3:2 are exactly the the same thing. The number 3 (numerator) is the first part, then subtract the demoninator
which is 5 into 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.) 80/100 = 0.8/1%x35 = 28
28/80 = 35/100

3.)
80/4=20 or 25% 80/10=8 or 10%

20+8=28 or 35%

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!

This blog http://linden8m.blogspot.com/ is the good.


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 is correct. She is correct because she has more kids than Ms. Lowrey. Ms. Stanzi had 40 kids and Ms. Lowrey had 25 kids, Ms. Stanzi would have 20 children that have met their reading goal of the month because 40 divided by 2 equals 20 or 50%. Ms. Lowrey would have 14 or 15 children that had met their reading goal because 39 divided by 100 is 0.39 and multiply is by 100 would give you 13.75. Ms. Stanzi can be correct.


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.
