Maybe I'm stupid but my daughter came home from school today with this math problem.
I thought the answer was C.9
but that means I have 24 ribbons in all?
Does not make since to me.
I think they have it worded wrong.

 

yeah the question is wrong, it would have to be an even number for the total.

 

Blue ribbons + yellow ribbons = 15 ribbons
X+(X+6)= 15
2X+ 6=15
2X=9
X=4.5

They didn't give you a correct answer in the choices. They also didn't think out that problem before hand for a 3rd grader. Perhaps a bit early for algebra and decimals combined....

Unless I'm wrong as well. And that is possible.

 

I agree with everything ofcmarc said. He is correct. A little too advanced for a third grader and they didn't give the correct answer as an option.

 

wow i looked at this for about 5 minutes before scrolling down and i thought i was just an idiot. maybe the 3rd graders should be making tests for the 40 year old math gurus

 

the question is either worded incorrectly or the correct answer(4.5) is not given... as written, this is a problem of 2 equations and one unknown and seems a bit advanced for a standard 3rd grade math class...

The question presumably should read:
Robyn has 6 more blue ribbons than yellow ribbons. If she has 15 blue ribbons, how may yellow ribbons does she have?

 

I think your right

 

I think you guys are over thinking this. My interpretation of the question is that she has 6 blue ribbons out of a total of 15 ribbons, how many yellow ribbons does she have. The answer is- C. 9.



Are we smarter than a 3rg grader?

She has 6 MORE blue ribbons than than yellow ones.

 

I see your math and would agree with it, "if" there were a disclaimer on the top of the page stating, "pick the most correct answer". I know things have changed since I have been in school, but as you previously stated, it is a little early for algebra and decimal points, (which I agree with you).


Tim

 

Tell her to go to school and tell the teacher she isn't going to do her homework if the teacher isn't gonna do theirs.

 

Now this is her homework for lastnight she was supposed to read this then answer questions on the back.
See anything wrong with it
This isn't the first time something like this has happened.

 

Time for a teacher parent conference. Shameful on the teachers part.


Good luck,


Tim
