1#Prescription calls for .24mg of a drug that you have in 50mcg/ml concentration. How many ml of liquid do you need?
#2You have a liquid that contains 12mg/10ml. What percent is this liquid? (Hint: To solve, you will need to convert mg to g per 100ml using decimals.)
#3And how would you convert 1 oz to grains?
Can you cross multiply to solve proportion equations or multiply by the reciprocal? I got confused the other day multiplyin by reciprocal because for instance i did 10/x=5/2 I multiplied by (X/10)(10/X)=(5/2)(X/10) - not sure if that works that way or if it is done by have the number over 1, and not the reciprocal. Was tryin to isolate the variables and this wasnt workin
