Or try it the long way- this always helped me to understand the concept & double check my answers. 1 grain = 60-65mg, you use whichever comes out with the even number usually. Unless instructed otherwise
Answer i believe would be 2ml. You use 1gr is to 60mg. So if it says 1/300 you would divide 60into 300 which equals 0.2. So 0.4mg is to x ml as 0.2 is to 1ml. 0.2x=0.4, 0.4 divided by 0.2 equals 2. I BELIEVE! But i did that in my head without double checking it so you definately should! Lol good luck
I start school for the first time next week and looking at this is like reading German. I'm terrified of math and this thread didn't help. Lol hopefully i have a good instructor that will make it easy.
