Question
2. Put brackets in the following expression to get the largest value possible. What problem solving strategy did you use?
AnswerCreate a problem that could be solved using the following expression..
I did (3x2.8)+6.4 divided by 4=
So 3x2.8=8.4+6.4 divided by 4 =10
Q

Question :

Annie has been asked to calculate 1.7+6 divided by 2. She claims the answer is 3.85. Do you agree? Explain why or why not.

Answer :

I dont because calculators arent always right maybe

she shoudlve use the B.E.D.M.A.S way .

Question :

Put brackets in the following expression to get the largest value possible. What problem solving Strategy did you use? 3 x 2.8 + 6.4 ÷ 4

Answer :

My answer is (3 x 2.8) + 6.4 ÷ 4 .

Strategy :

6.4 + 6.4 ÷ 4

8.4 + 1.6

10

1. Annie has been ask to calculate 1.7+6/2 she claims the answer is 3.83 do you agree ? why or why not ?

2. I don't agree because she didn't follow BEDMAS because division come before adding so she should on got 4.7












Put brackets in the following expression to get the largest value possible what problem solving strategy did you use 3x2.8+6.4\4

1. (3x2.8)+6.4\4=10 .

create a problem that could be solved using the following expression 2.5 +1.25+5 x1.6

Kyia wanted to get a pack of Kit-Kat's they cost 11.75 and she only had 9 dollars so she started to sing and she got 2 dollars but she still needed 75 cents so she looked around out and got 75 cents and now she can buy Kit-Kat's

So Annie has been asked to calculate 1.7+6 divided by 2. She claims the answer is 3.85. Do you agree why or why not.

Did u think of it?

If you did the question the answer is incorret because if she did the B.E.D.M.A.S her answer well be 4.7 not 3.85

I got that answer because you have to do 6 divided by 2 = 3 then 3 +1.7=4.7

Hope you like it !!!!!!

This is an example we did in class:









1.) Annie has been asked to calculate 1.7+6 divided by 2.

She claims that the answer is 3.85. Do you agree? Explain why or why not.



My answer. ) I don't agree because I think she didn't use B.E.D.M.A.S. If she used it then her answer would be 4.7.



Here's how I got that answer:




2.) Put brackets in the following expression to get the largest value possible. What problem solving strategy did you use? 3x2.8+6.4 divided by 4

My Answer) (3x2.8) + 6.4 divided by 4 =
6.4 + 6.4 divided by 4 =
8.4 + 1.6 =
10

3) Create a problem that could be solved using the following expression. 2.5 + 1.25 + 5 x 1.6.

Solution: Jimmy wanted to buy something for his sister's birthday and he found a very nice bracelet that costs 11.75. He went back home to see how much money he had in his wallet, he only had 1.50 so he was 8 dollars short. Jimmy really wanted to get the bracelet for his sister, but he didn't have enough money .. so he had to ask his mom or dad. His parents said that he had to either sell 5 of his things for 1.60 each or do 5 chores for 1.60 each. He chose to sell 5 of his things very quickly before his sister finds out, within 2 hours he had enough to buy the bracelet for his sister!
