Question 1 :

Annie has been asked to calculate 1.7 + 6/2 .

She claims the answer to be 3.85.

Do you agree ? Explain why or why not .

Answer :

Annie only got 3.85 because she didn't use BEDMASS.

She got the answer 3.85 this way :

1.7 + 6 = 7.7

7.7/2 = 3.85

The real answer should have been :

1.7+6/2

6/2 = 3

1.7 + 3 = 4.7

Question 2 :

Put the brackets in the following expression to get the largest value possible .

What problem solving strategy did you use ?

Answer :

I have put the brackets between in the question like this : ( 3 x 2.8 ) + 6.4/4 =

The answer would be 10 which is the largest value you can get !

I have used BEDMASS to solve this problem .

Question 3 :

Create a problem that could be solved using the following expression :

2.5 + 1.25 + 5 x 1.6

Answer :

John is selling pie for her class fundraiser.

One small pie is $ 2.5.

But if you buy 2 pies you can get them for $ 1.25.

And also john has a sign that says :

If you buy 3 pies you get them for $1.6.

Five people came and each got 3 pies each.

Corrections for number 22

So to start off this scribe post is i am going to tell you the question which is :

Use the coodinate grid shown to do the following:

A) Rotate squareABC 90' in a counterclockwise direction about the centre of rotation C.

B) Translate squareA'B'C' 3 units right and 3 units down.

C) What are the coodinates of B'' ?



What they are saying is that after you had translated it 3units right and 3 units down , you made you new A''B''C''. Now C) is pretty easy you just look and lable the coodinates !

Corrections to question 22

So the start off this scribe post i am going to tell you the question first , which is :
Use the coordinate grid shown to do to following :
A) Rotate squareABC 90' in a counterclockwise direction about centre of rotation C.
B) Translate squareA'B'C' 3 units right and 3 units down.
C) What are the coordinates of B'' ?

What they are saying is after you rotated 90' counterclockwise the coordinates have to be at:

A') ( -5,0)

B') (-2,3)

C') ( -2,0)

and have moved it 3 units right and 3 units down ,you can see A'' , B'' , C'' and they are saying what are the coordinates of B''. You should get the answer really easy on C .
