(Textbook questions 1,5,9,15 on pgs.128 and 129.)

Question 1:

Use hundred grids and words to describe the similarities and differences between a percent less than 1%, a percent between 1% and 100%, and a percent greater than 100%.

Differences: They all have different values.

ex. 1/2% is not just a fraction of 100% but a fraction of 1%.

Similarities: They all represents hundredths.

ex. 50% is less than 100% but 125% is more than 100% but they are both hundredths.

Question 5:

What percent is represented by each diagram if a completely shaded grid represents 100%?

a= 3/8%

b=125 1/2%

c=282%

Question 9:

Give two examples where a percent greater than 100% might be found in everyday life.

1- When you take a test that you can receive bonus marks on.

2-When you put a 110% effort into your basketball game.

Question 15:

Show how hundred grid(s) could be used to represent a very small percent such as 0.0000125.

Here is a LINK that could help you with percents.

I couldn't find any percent videos that invloves the things were are learning now.
