### Stephanie'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.

It is an equivalent fraction out of 100 you will know it is a percent because you'll see this sign after the number %

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 all equivalents.
Because 3:2 , you add the two numbers together and you get 5 and that is the denominator and the first number of the ratio is the numerator so it's 3.
Then i would be 3/5.So both are the same value.
Now 60% is the same to all of these because to find a percent you have to divide numberator(3) by the denomenator (5) then you multiply it by 100 and you get 60% (n/d*100=%).
So that means it is similar because 3/5 = 0.6 * 100 = 60%.

Question 3;

Show 3 different ways to fine 35% of 80.There are 100 squares in each:100 divided by it gives you 1%. So its 80 divided by 100 which equals 0.80.8 is how much one area of a square equals.

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: 40/2=20

Ms. Lowrey: 40/1.5=26.66

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?

I did it On PAPER =P
