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

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
