Written as: 20 mg:1ml =15 mg :x ml
Remove the mg and mls
Now you have 20:1 = 15:x
20 times x = 20x (multiply your two outer numbers)
1 times 15 = 15 (multiply your two inner numbers)
remove the x from 20
15 divided by 20 = 0.75
So, the formula is:
My instructor always laughed at me -said I was doing the formula backwards BUT as long as it worked it was OK! As I look at it now, it appears hard but it's really not! Take your time and break it down. I still use this today...Good luck!
