The formula for the first one is = 75/10=1500/x.....cross multiply those

i got 1.5/x = 750mg/10 and got 0.02 mL

Its not 1.5 its 1500 you have to convert gram to mg

Think about it you have 750mg but need 1500 mg..I..so you need 2 of the 750mg doses. If they are in 10mls ..it would be 20mls

In your formula..all units of measure must match to cross multiply..its easy to forget to convert

Try to do the questions and tell us what you have come up with.Just getting us to give you the answers won't help you learn.

Try numbers 6 & 7. Those are easy ones to start off with.
