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!

This post talks about percentages. Per means 'part' and cent means 'for every hundred'. Percentages are a lot like ratios because they are both comparing multiple numbers.
A percentage formula would look like this:
Numerator divided by denominator=decimal multiplied by 100=_%
Others should read this post because it can help them if they don't understand percentages.

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 because 50% of any number is always half and 55% of any number is more than half. Ms.Stanzi could be wrong because it doesn't matter what number or how big that number is.

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?

BubbleShare

16 is 40% of 40

b) What is 120% of 30?

BubbleShare

120% of 30
120 divided by 100=1.2
1.2 multiplied by 30=36
120% of 30=36

I Marked and Commented On:
Julie Rose 8-16 I gave it a 60 out of 65.
