### Marielle'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.)

(if the pictures don't work, click the link)
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.
They are all the same because they are all equivalent to eachother.

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).

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!

^^is a post i commented on. This post talked about decimals, percents, and fractions. You should look at this post if you want to learn how to convert decimals to percents, percents to decimals and percents to fractions.

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.
There's 2 ways of answering this question.
1)Ms.Stanzi might, be right if she has a greater amount of students than Ms.Lowrey. It doesn't really matter on how many students Ms.Lowrey may have (in percents); Ms. Stanzi's class will always have a greater amount of students that met their reading goals.
2)My second answer is that Ms.Stanzi might also be right if she has the same number of students in her class as Ms.Lowrey.If it were, then Ms.Lowrey's class would have a greater amount of students who reached their reading goal. It would be so because 55% is obviously larger than 50%

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?
40 stands for the number of squares shaded in. the 16 stands for how much the 40 squares are worth. The first thing we do is we put these numbers into a fraction = 16/40 . Then we divide 16 by 40 which would equal 0.40 (1 square or 1%). After that we multiply 0.40 by 100 which equals 40. The whole unit square is worth 40.

b) What is 120% of 30?
If we were to put this in a fraction, the numerator will be larger than the denominator because 120% is bigger than 100%. First we find 1% or 1 square by dividing 100 by 30 which is 0.3. We then multiply 1.20 by 1% (0.3) which equals to 36. 120% of 30 is 36/30.
