1) What type of ratio terms are the numbers 1, 2, 3 and 4.
2) Give an example of an equivalent fraction.
3) Give an example of a simplified fraction.
Don't forget to study for the ratio test on Wednesday. Don't forget to study the numbers Harbeck gave us in the homework book.
Harbeck told us to make a scribepost on the test.
1)What were the mistakes you made on your test?
Some of the mistakes I made on the test were Question #18.
The question was...
In a student election Carol gets 60% of the voted. If there were 485 votes cast, how many votes did carol get.
My answer was this.
0.595 x 100=59.5
carol got 289 votes
My mistake was forgetting to use a table ratio.
I will remeber that when you get a percentage question you should use a ratio table.
