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.)
A percent is part of 100 and it has the percent sign%.


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.
They are all the same because if you would to convert them all into decimals they should all be the same.
3/5= 3 divided by 5=0.6
3:2= 3/5= 3 divided by 5= 0.6
60%= 60 divided by 100= 0.6
0.6= 0.6

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. First we have to find what 1% equals. 80 divided by 100 = o.8 or 1%. 0.8x35=28. So 35% of 80 is 28. So you know that your answere is right you could make fractions then convert them into decimals.
35/100=0.35 and 28/80=0.35
2.
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!
I have left a comment on someones post about intrest.On this post they explained about intrest.Interest is the money you pay back when you borrow money from the bank.
It is a formula of Principal x Rate x Time.
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 of she had more children in her class than Ms Lowrey's 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?
40 divided by 40 =1%
16 divided bye 40=0.4
0.4 x 100= 40
40/100= o.4 is the same as 16/40= 0.4


b) What is 120% of 30?
120 divided 100= 1.2 or 1%
1.2 x 30=36
36 is 120% of 30.
36/120=0.3 is the same as 30/100= o.3
