< color="#ff0000"> What is a good defintion 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 definiton)
A percent is a number out of 100.
eg. 55/100 = 55%
the symbol for percent is known as : " % "

question 2: How are three fifths (3/5), 3:2, 60% and 0.3 all the same? Use pictures and words to show your answer.
3/5 (numerator divided by denominator is the fraction)
3 / 5 = 0.6
0.6 x 100 = 60%
3:2 (3 is the numerator) (3+2=5 = 3/5)

question 3: Show 3 different ways to find 35% of 80 (BUBBLESHARE is an excellent tool to animate the many different ways).
1.100 % 80 = 8 x 35 = 280
2.10 + 10 + 10 + 5 8 + 8 + 8 + 4
----------------------- = -------------------
35/100 28/80
3. 25 + 10 = 35
80 % 4 = 20
80 % 10 = 8
25 = 20
8 = 10
20 + 8 = 28

question 4: find a link to blogs that deal with percentages. Leave a comment behind and add the link witha 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 post is about Percentages. It reviews many ways to get percents. others should read this because if you don't understand how to get a percent, this will show you how.

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. ws 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.

ms. stanzi 36 kids in her class and ms. lowrey 30 kids in her class. ms. stanzi's class has 18 kids that met their reading goal. (36 ÷ 2=18)
(30÷100=0.3, 0.3x55=16.5)

ms. stanzi is not correct.

Hey Jerica you would get a better mark if you put the labels. (growing post, percents) And the Title should be Jerica's Percentage Growing Post. Also you forgot question 5 and 6.
