Help with Math, Please.....

Hi how is everyone doing? I am praticing some clinical dosage math problems, and have encountered trouble with two. I have been trying to solve them for a long period of time, but just don't get to the solution. Is it possible, if someone can tell me if I got the right answers. Thanks!!!!

#1 asks how many mls you would give. It states there are 10mg per teaspoon. One teaspoon equals 5 mls so you have 10mg/5ml.You would give 12.5 mls for a dose of 25mg.

The question asks for how many mls you would give so you can't give the answer in teaspoons.
