### rivka's percentage growing post

Question #1:
What is a good definition of percent? You should use words, symbols, pictures and numerical example for your definition.

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 is same as 3:2, 60% and 0.6 because when you convert 3/5 into ratio the answer is 3:2, when you convert the 3/5 to percent the answer is 60% and when you convert the 3/5 into decimal the answer is 0.6. look at the pictures so you can understand it better!

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) 80/100=0.8
0.8x35=28

2)80/4=20 25%=20
80/10=8 10%=8

3)100 / 100 = 1
80 / 100 = 0.8
0.8 x 35 = 28
28 / 80 = 35 / 100

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 found a link that deals with percentages. I really think that the scriber of this post really did a great job. this is the link:

people should read this post because:
1)it really helps you if you dont understand percenatges.
2)it tells how to convert fraction to percent.
3)it tells how to ge the lowest term of a fraction.

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.

for me Ms. Stanzi is right because the number of the children in her class is probably more than the number of the children in Ms. Lowrey's class. im going to give you an example.. let's say that the representing number of Ms. Stanzi's class is 30. the number of 50% of 30 is 15. then in Ms. Lowrey's class the representing number is 25. the number of 55% of 25 is 13.75. so it means that Ms. Stanzi's right, but if you're going to use different numbers Ms. Stanzi can be wrong.

a) 16 is 40% of what number?
