### Leslie'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.

Percent: An equivalent that is written as a fraction with a denominator of one hundred.

Example 50% would be 50/100, fifty over one hundred, half of a whole.

Question 2
How are three fifths (3/5), 3:2, 60% and 0.6 all the same? Use pictures and words to show

60% = 60/100 60 divide by 20 = 3 3/5

=100 divide by 20 = 5

60%= 60 divide by 100 = 0.60

3/5= 3:5-3= 3:2

I got 3/5 from 60% by dividing the numerator and the denominator by 100.
I got 0.60 from 60% by dividing 60% by 100.

I got 3:2 by taking away the numerator from the denominator (5-3) which equals 2 and the first # is always the numerator.

Question 3

Show 3 different ways to find 35% of 80.

100 divided by 100=1

80 divided by 100=0.80

Each square equals .80

35*.80= 28%

35/2=17.5

17.5*0.8=14

14+14=28

80/10=8
10/2=5
8~10
8~10
8~10
4~5
28~35

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 can be correct because she could have more children than Ms. Lowrey in her class.

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?

You have a 10 by 10 grid. It's percentage isn't 100% it is a lower number because 16 is smaller than 40. I coloured in 40 squares because it asks for 40%. So Mr. H wants to know what number has 16 that is equal 40%. This is what i came up with:

40/100=.4
.4*40=16
So the square is worth 40
40=100%
16=40%

B) What is 120% of 30?

I have 2 10x10 grid. I coloured them in to equal to 120. What I need to find out is how much 120% is when the total number is out 30. This is what i came up with:

30x120%=3600
3600/100=36
120%=36
