Ashley's Growing Post

1. What is a good definition of percent? You should use words, symbols, pictures and numerical examples in your definition.
A percent is an equivalent fraction out of 100. example: 50% = 50/100.

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 equivalents. For 3:2 you have to add the numbers together so you get 5. 5 is the denominator and 3 is the numerator. 3/5.
3/5 equals 0.6
To get a percent it is numerator divided by denominator times 100. So it is 60%.

3. Show 3 different ways to find 35% of 80.
1. 100 divided by 100 = 1%
35 divided by 35= 1%
35 divided by 100 = 0.35
0.35 times 80 = 28

2. 100 divided by 100 = 1%
80 divided by 100 = 0.8

3. 80 divided by 100 = 0.8
each square is worth 0.8

4.Find a link to blogs that deal with percentages. Leave a comment behind and add the link with a review.

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?
I think Ms. Stanzi is correct because there is more children in Ms. Lowery's class.
20/40 = 50%
11/20 = 55%

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?
40% of 100 is 40
40/100 = 0.4
16 x 0.4 = 40
40/100 = 16/40

120% of 100 is 120/100
120/ 100= 1.2
100 = 30
30 x 1.2 = 36
120/100 = 36/30

Comment: Next time you make a post make sure you try some of the tools. Try to use bubbleshare and gliffy. Bubbleshare is really easy if you have paint on your cumputer. Because when you put pics its easier for people to understand and it makes your post look colourfull. =)
