The assignment is Compare Estimated Quotients

1) $46.35/3 and $81.35/5
Round $46.35 to $50/3=16.666
Round $81.35 to $80/5=16
16.666 is greater than 16

2)$7.27/13 and $9.08 divided by 19
Round $7.27 to $7/13=0.538
Round $9.08 to $9/19=0.473
0.538 is greater than 0.473

3)8.2/12 and 7.3/14
Round 8.2 to 8/12=0.666
Round 7.3 to 7/14=0.5
0.666 is greater than 0.5

Can you tell me please if the above answers are right or wrong and point out any mistakes if any.

1.No. Your estimate would be closer if you'd followed my advice in an earlier post.

2. Yes.

3. Yes.

I will go back and try number 1 again and relook at that one and will then post my second answer.
Answered by Patrick
So instead for number 1 you would do the following:

$46.35/3 and $81.35/5
Round $46.35 to $46/3=15.333
Round $81.35 to $81/5=16.2
so then 15.333 is less than 16.2

You're right. But it would be easier to round to 45 and 80.

Answered by Patrick
So what you are saying is try to get a number that the lower number such as 3 or 5 can be able to better divide into.
Answered by Patrick
I think I may have a tad bit of a better understanding so like with the below:

276.3/9 and 389.4/5
276.3 would be rounded to 270/9=30
389.4 would be rounded to 400/5=80
so 30 would be less than 80
