Myrh Rynn'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.

-A percent is an equivalent fraction out of 100.

-Percents can be converted into fractions, decimals or ratios.

-% is the symbol used to represent percents

-to convert a fraction into a percent, you have to divide the numerator by the denominator 1/4 is the fraction (1\4=0.25) then you have to multiply the answer by 100 (0.25x100=25%)

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 left my comment at https://www2.blogger.com/comment.g?blogID=33406999&postID=116474431867734886 .It was very easy to understand and it explained a lot about percents. Someone who didn't know anything about percents would know what they were talking about after they read this post.

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?
Yes, Ms Stanzi could be correct because the principle did not say how many children were in each class. It would depend on how many students were in each class.

Let's say Ms Stanzi had 40 students and Ms Lowrey had 20.

20 of Ms Stanzi's students met their reading goal. (40/2=20)
11 of Ms Lowrey's students met their reading goal. (20/100=0.2x55=11)

In this case Ms Stanzi would be correct.

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?

b)What is 120% of 30?
