20 mg / 5 ml = 10 mg / 2.5 ml

So 30 mg = 7.5 ml

Maybe you should review some proportions and such since that is a lot of medication calculation. Youtube often has helpful videos.

break it down ---> how many mg in 1 mL? then you can divide the ordered mg by the supplied mg/ml.

Actually you REALLY need to review proportions. Medication calculation is life or death in some situations and you can't get on here and ask for help.

Just some perspective. But practice makes perfect so just put in that extra effort to make sure you know how to figure these things out.
