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 is the post i left a comment on : http://linden8m.blogspot.com/

This post shows you how to convert a percent to a decimal, decimal to percent and percent to fraction. It is explained very clearly for you to understand how to convert 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.

Ms. Stanzi can be correct or can't be correct. It all depends on exactly how many students are in the class. If Ms. Stanzi's has 20 and Ms. Lowrey's has 40. Ms. Stanzi has 50% of her students that met their goal, so that's 10 students out of 20. Ms. Lowrey has 55% of her students that met their goal, so that's 22 students out of 40. In this case, Ms. Stanzi is not correct, since she has only 10 out of 20 students that met their goal and Ms. Lowrey has 22 out of 40 that met their goal.

Now if we turn the numbers around and make Ms. Stanzi's class have 40 and Ms. Lowrey's class have 20. Ms. Stanzi would be correct about having more students that met their 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.

b) What is 120% of 30?
