### Growing Post by Nathaniel in the class of Mr. R, Penner of room 8-16 .

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.)

Answer : A percent , is a fraction out of 100 . It is part of a whole . It can be converted into a ratio , fraction or a decimal .

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.

Answer : Three fifths , 3:2 , 60 % and 0.6 are all the same because it is all 60 % . Or 60 parts out of 100 .

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).

Number 1 :

100 / 100 = 1
80 / 100 = 0.8
0.8 x 35 = 28

Number 2 :

80 / 2 = 40 = 50 %
40 / 2 = 4 = 5 %
40 - 4 - 4 - 4 = 28
50% - 5% - 5% - 5% = 35%

Number 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!

Answer : http://linden8z.blogspot.com/ is where i commented . My comment hasn't been accepted yet . The post had explained three ways on how to find the percent . She/He had done stuff we did in class . But had explained it thoroughly which could make someone understand it pretty easy .

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.

Answer : Ms. Stanzi's is right . She can have a greater amount of STUDENTS that met their goal . It doesn't relate to their percent as much . For example : Ms.Stanzi could have , 1000 students . Which means 500/50% of them met their goal . Ms Lowrey can have 100 kids , which means 55/55% students have met their goal . So yes , she is correct . And congratulations to Ms. Stanzi's class for being able to read .

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./ 16 is 40% of what number ?
....
40 / 40 = 1
16 / 40 = 0.4
0.4 x 100 = 40
16 40
_________
40 100

B./ What is 120% of 30?
....
Finish up later . Bed time :)
