### Anna'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. (suggestion gliffy is an excellent tool for adding detail to your definition.)

A percentage is an equivalent fraction that is out of 100. Percentages can be converted into decimals, ratios, and fractions. And so on... Here is a web that shows you what you can do with a percentage. Click here.

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.

Question 3
Show 3 different ways to find 35% of 80. (bubbleshare is an excellent tool to animate the many different ways of finding these answer).

BubbleShare

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 chose the first post because it was talking about percentages. He explained how to get a percent very good. Also he said, why should other people read the post, and I think it could help other people like me.

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 could be right if she has more children in her class.

Example:
Ms. Stanzi has 36 kids in her class and Ms. Lowrey has 30 kids in her class. Ms. Stanzi's class has 18 kids that met their reading goal. (36 ÷ 2=18)
While Ms. Lowrey's class only had 16 or 17 kids that met their goal . (30÷100=0.3, 0.3x55=16.5)

Therefore, Ms. Stanzi is not 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.

a) 16 is 40% of what number?

b) What is 120% of 30?
30 ÷ 100 = 0.3
0.3 x 120 = 36
120 % of 30 is 36.
