There were 340,000 cattle placed on feed. write an equivalent ratio that could be used to find how many of these cattle were between 700 and 799 pounds. how many of the 340,000 cattle placed on feed were between 700 and 799 pounds

We see this same problem pop up here on every
couple of months.  Nobody yet has ever given us enough
information to answer it. 

There's no information here that we can use to find out the
weight of any of the cattle placed on feed.  There must be
some more information BEFORE this. 

Maybe it's in the previous question in the book or on the
homework sheet, and nobody who posts this question ever
includes the information from the question before it.

Sorry i really need my points
