Marygrace's Growing Post ..

Question 1:
What is a good definition of percent? You should use words, symbols, pictures and numerical examples in your definition.
One part in a hundred. For example, 62 percent (also written 62%) means 62 parts out of 100.





Question 2:
How are three fifths (3/5), 3:2, 60% and 6.0 all the same? Use pictures and wods to show your answer.
Question 3:

This blog talked about 3 different ways to find the 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 cannot 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?
b) What is 120% of 30?


a) 80

16 / 40 = 0.4 0.4 x 100 = 40 16 / 40 = 40% / 100
16 / 40 is equivalent to 40 / 100 because when you divide both of them, they both are 0.4.




b) 30
30 / 30 = 1%
120 / 30 = 4
1 square is worth 4.
4 x 120 = 480
30 is equal to 100. To find 120% of 30, you have to divide the percent by 30. 120 divided by 30 equals 4. The 4 is equal to 1%. Then you multiply 4 by 120 to get your answer. (4 x 120 = 480)
