Lalopoulou's Growing Post

1) What is a good definition of percent?
A good definition of percent is:
It is an equivalent that is written as a fraction out of 100

2) How are three fifths (3/5), 3:2, 60% and 0.6 all the same?
3/5, 3:2, 60%, and 0.6 are all the same becasue they are all equivalent to each other

3) Show 3 different ways to find 35% of 80.
60% = 60/100 60 divide by 20 = 3 3/5
=100 divide by 20 = 5
60%= 60 divide by 100 = 0.60
3/5= 3:5-3= 3:2
I got 3/5 from 60% by dividing the numerator and the denominator by 100.
I got 0.60 from 60% by dividing 60% by 100.
Then I got 3:2 by taking away the numerator from the denominator (5-3) which equals 2 and the first number is always the numerator.

4) Find a link to blogs that deal with percentages. Leave a comment behind and add the link with a review. This is the blog I left a comment on. I actually thought it was kinda interesting! =D

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 she could have more kids in her class than Ms. Lowrey.

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?

a) 40% of 100 is:

40 40/100=0.416 x 0.4=40 40/100 = 16/40

I got this answer by first dividing 40 by 100 and that gives me 0.4. So then you multiply the decimal by the part and that gives you 40% of 16.

b) 120% of 100 is 120120/100=1.230 x 1.2=36120/100 = 36/30

First I found out what 120% of 100 is which is 120. So then I divided 120 by 100 which gives me 1.2. Then you multiply by the whole which is 30 by 1.2, and that gives you 36 out of 30.
