Hi, this is Drew
Today in Math we set a date for the test which is on Thursday, October 29th.
We also did the chapter review on pages 70, 71 (due up to #15) and a quiz on the smart board to prepare for the test.
Mr. O explained that you can solve a question using a unit rate, in which the bottom number is reduced to 1, by dividing the top and bottom number by the same amount (ex. divide the numerator and the denominator by the denominator)
ex. if 5 cans of soup cost $3.00, how much is one can worth?
$3.00/5cans - so when you divide both the numerator and denominator by 5 the answer is $0.60/1 or 60 cents for one can.
The other way is using a proportion, which you set up with the two rates side by side with the unknown number represented by an X. You then multiply diagonally the two numbers that don't have an X and then divide the product by the remaining number to find the value of X.
We also learned that only ratios can have a percent. You get this by adding all the numbers in the ratio together and then dividing one number into the total number to get a percent ex. ratio=5:10, 5+10=15, 5/15=33.3..............%.

ReplyDeleteWell done Drew! A great start for others to follow. Hopefully, we will continue to all learn together - both our math and blogging skills - and in a month or so, this blog will have really moved forward.

ReplyDeletesweet mr.o we should use it for different classes too
ReplyDeleteHey today we corrected the Chapter Review. Some people had some trouble with number thirteen. We have a test tommorow and I feel positive about it, I don't know about everyone else but I do.
