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

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%

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
