Ardia's growing post =P

Question 1
What is a good definition of percent? You should use words symbols, pictures and numerical examples in your definition.


-- the picture says it all ..









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.


3/5 equals 3:2 becuase 3+2 = 5 and 5 is the denominator of the fraction


3/5 equals 60% becuase 5 divided by 3 is 0.6 and 0.6 x 100 is 60%


3/5 equals 0.6 because 5 divided by 3 is 0.6

long story short .. they're all equivalent to each other =)


Question 3

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 cant be correct because her class's percentage is lower than Ms. Lowery's.
She could also be correct because she could have more students than Ms. Lowery's class.

Let's say Ms. Stanzi's class at 10 students. 10 / 2 = 5 5 = 50%

.. and Ms. Lowery's class only has 6 students ..

6 / 2 = 3 0.5 / 6 = .08 3 + .08 = 3.08

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?

if 16 is 40% of a number you divide the number by 4 so you can get 10% and in this case it is 4 .. so to get 100 percent you need to multiply it by 10 becuase 10 X 10 = 100 .. so 4X10=40 so 16 is 40% of 40









b) What is 120% of 30?

30 is 100% so all we need to find 20% .. in the picture I found 1% but there is a shorter way .. find 10% first so 30/10=3 or 10% so 3(or 10%) X 2 = 6 (or 20%) so 120% of 30 is 36
