Peggy'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 percent is a number that is part of a whole, 100%. Percents can be converted into a fraction, decimal or into a ratio.



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.




RATIO TO FRACTION: 3:2 ( 3+2=5 )=3/5



FRACTION TO DECIMAL: 3/5=3÷5=0.6
DECIMAL TO PERCENT: 3÷5=0.60.6x100=60
They are all the same because they all equal 60% when you convert them.




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).




1) 35% of 80



80÷100=0.8



0.8x35=28







2) 0.35x80=28



35÷100=0.35



0.35x80=28







3) 28/80=35/100



28÷80=0.35



35÷100=0.35






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!




I chose to comment on this blog " http://linden8z.blogspot.com/2006/11/percentages-real-deal.html " because it explains a lot about percents. It teaches you how to reduce percents to its lowest terms and has a great use of pictures that almost motivate you to want to learn more about percents.




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 correct, even though 55% of Ms.Lowrey's class met their reading goal does not mean that more kids in her class met their goal. Because Ms.Stanzi could have more kids than Ms.Lowrey's class.



Example : 10 kids in ms. stanzi's class



10÷2 = 5 = 50%



ms.lowrey's class



12÷100=0.12x55=6.6


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?


a) 40÷40=116

116÷40=0.40

16/40=40/100




b) 30÷100=0.30

3x120=36

36/30=120/100
