### Michael's Percentage Growing Post [V 1.3]

QUESTION.1
"What is a good definition of percent? You should use words, symbols, pictures and numerical examples in your
definition. (sugesstion gliffy is an excellent tool for adding detail to your definition."

Percent: "equivalent that is written as a fraction out of 10"

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 all equal:

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)."

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!"

Here is a post on 8Z math that i commented on. It really helps for answering question 3 on our growing posts. It explains 3 different ways to find a percent.

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."

She CAN be correct because there can be more students in half of Ms. Stanzi's class than in 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?
The question asks us to find out what has 16 as 40%. To do this is simple. First we know that 40% + 40% + 20% = 100%. So since we already know that 16 = 40% of x, we just need to know what 20% is. To do that divide 40% by 2. (40%/2 = 20%). So 16/2 = 8, so we can say that 8 is 20% of x. And now we add everything together. 16 + 16 + 8 = 40. There. Now we know that x = 40, so 16 is 40% of 40.

b) What is 120% of 30?"
This one is easier than A. We know that 30 is 100% of 30. So we just need to add 20%. Just go...(30/100 = 0.3 x 20 = 6) So 30 + 6 = 36 and we conclude that 120% of 30 is 36.
