### Julie Rose // 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.)

Examples
1.)1/2 = 1 divided by 2 = 0.5 x 100 = 50%
2.)1/4 = 1 divided by 4 = 0.25 x 100 = 25%
3.)3/4 = 3 divided by 4 = 0.75 x 100 = 75%
4.)5/35 = 5 divided by 35 = 0.142 x 100 = 14.2%

- - - - - - - - - - - - - - - - - - - -

other way you can show percents: ^^ im still gonna use the numbers from my example

1.) 1/2 is the same as 50/100
2.)1/4 is the same as 25/100
3.)3/4 is the same as 75/100
4.)5/35 is the same as 14.2/100

**how would you know if it's the same?!?!... you would know it because if you divide both the numerator and the denominator together you get the same answer
**

for example:

•8/36 = 8 divided by 36 = 0.222 x 100 = 22.2%
•22.2/100 = 22.2 divided by 100 = 0.222
8 __ 22.2
-- = ---- = 0.222
36 _ 100

- - - - - - - - - - - - - - - - - - - -

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.

•3/5 = 3 divided by 5 = 0.6 x 100 = 60%
•3:2 = 3/5 = 3 divided by 5 = 0.6 x 100 = 60%
•60% = 60%
•0.6 x 100 = 60%

** If you convert them all into percent you get 60%. That is how they're all the same**

- - - - - - - - - - - - - - - - - - - -

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 way:

•100 divided by 100 = 1
•80 divided by 100 = 0.8
•0.8 = 1%
•0.8 x 35 = 28%

2nd way:

•28/80 = 35/100
-------------------------
•28 divided by 80 = 0.35
•35 divided by 100 = 0.35

3rd way:

•28/50 = 35/100
•35 divided by a 100 = 0.35
•0.35 x 80 = 28%

Question 4

Find a link to blogs that deal with percentages. Leave a comment behind and add the link with the review (What the post was talking about....yes you have to the post and why other 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 here. is a review of percent. it shows you how to get percent in different ways. this person used pictures to explain the work.

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. If she had a class of 45 and 50% of her students met the reading goal then she is right because if Ms. Lowery had a class of 30 and 55% of her class met the reading goal Ms. Stanzi's class achieved the goal because even though Ms. Lowery's class had a higher percent (55%) Ms. Stanzi has more kids than her.••••
------------------------------
Ms. Stanzi
------------------------------
•100 divided by 100 = 1
•45 divided by 100 = 0.45
•0.45 = 1%
•0.45 x 50 = 22.5
•22.5/45 = 50/100
------------------------------
Ms. Lowery
------------------------------
•100 divided by 100 = 1
•30 divided by 100 = 0.3
•0.3 x 55 = 16.5
•16.5/30 = 55/100
------------------------------
••••Ms. Stanzi could also be wrong if Ms. Lowery had a greater number of students in her class than Ms. Stanzi••••
------------------------------
for example.....
------------------------------
Ms. Stanzi had 40 students and Ms Lowery had 30.
------------------------------
Ms. Stanzi
•••• •••• ••••
1) 40=100
2) 40/2=20
3) 20=50%
•••• •••• ••••
Ms. Lowery
•••• •••• ••••
1) 30=100
2) 30/2 =15
3) 30/2.5=12
4) 20+12=32
••••••••••••••••

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?
