I know right. My teacher doesnt know how to asnwer this one. That is why I am asking you guys. Please help.

Just need a few assumptions,  like the ruler has marks every .5 cm.  Then the error is 1 cm in 7.

Well, it says find the "error", probably you typed something wrong...XD
But, umm, this question just makes no sense, @Redcan...I would probably suggests you get a special tutor or something. :\

opps, .5 cm in 7. you can read to at most .25 cm accuracy on either side of 7.  so .5/7 = 7.14

anonymous · Answer

If you have a ruler with mm marks, .01/7.

@Vickyisthesmartone123 I think the question makes sense, error estimation is a standard problem, and question.  How accurate is your measuring device. What is the max error.

Thank You @Redcan

The question, as presented, does NOT make sense.  You cannot say it makes sense and then add the additional information that would make it make sense.  THAT makes no sense.
