Michael'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. (suggestion gliffy is an excellent tool for adding detail to your definition.)

A percent is an equivalent fraction out of 100













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 the same because they are equivalent. They are equivalent because if u turn the ratio into a fraction of 3/5 and then divide 3 by 5 is 0.6 as a decimal. Then multiply the decimal to get 60% thats why3/5, 3:2, 60% and 0.6 are all the same.














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) 35% of 80 80/100=0.8 0.8x35=28 2) 100/1=100 80/1=80 0.8x35=28 3) 28 over 80 = 35 over 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!
http://www.hostsrv.com/webmab/app1/MSP/quickmath/02/pageGenerate?site=quickmath&s1=numbers&s2=percentages&s3=basic This is a good website for percentages because it tells u how to use percentages and what is it. It also tells u answers of any questions.
Its easy to use so try it out !

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 right. She could right because she might have more kids than Ms. Lowrey. For example, If Ms Stanzi had 34 kids in her class 17 students(34/2=17) in her class must have met their reading goal.


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?

We're trying to find 40% of some number is 16. In order to answer this question. We first need to find what 1% of this number then multiply the value of 1% by 100.













^ a grid of 10 x 10 grid

b)
What is 120% of 30?
