Question 1:What is a good definition of percent? You should use words, symbols, pictures and numerical examples in your definition.
A percent is a fraction of 100. The symbol % means 100 in french.
example:55/100 = 55%

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 the same because if you make them all a percent it will be all the same. For example 3:2 and 3/5 are the same because when you convert 3:2 it will be 3/5. 3/3+2=5 then that is 3:2. 60% is the same as o.6 because 0.6 converted into a % is 60 and 60% converted to a decimal is 0.6.

Question 3
Show 3 different ways to find 35% of 80.
1. 35/35= 1%
35/100=0.35
0.35/80=28 /100

2. 100/100=1% 80 divided by 100 = 0.8

3. 80/100=0.8

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
I she correct because there is more children in Ms. Lowery's class.
20/40 = 50%
11/20 = 55%

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?

40/40=1%
40/100=0.4
0.4x100=40
40/100 = 16/40

120/120=1%
120/100=1.2
100=30
1.2x30=36
120/100 = 36/30
