 How ? by: Anonymous I still don't understand how this is solved. Why did you set the problem up this way? Thanks for any extra information.

 Answer by: Anonymous gtt= 60gtts * 250mL * 15units =--- -- --- ---min= mL 25000units minCross out ml and units and you will have gtts and mins. That is what they are looking for.Do multipying across top with Numerators, then multiply across bottom with denominators. Answer will be 225000 ------ 2500 This is division, your answer should be 90, the answer will be 90 gtts/min
