k

OpenStudy (anonymous):

Do u know what to do next?

OpenStudy (anonymous):

i thought you would multiply 10 x .4, which equals 4.

OpenStudy (anonymous):

i dont understand why youre adding.

OpenStudy (anonymous):

hang on i am confused now

OpenStudy (anonymous):

Hint hint, you should divide...

OpenStudy (anonymous):

oh ya u need to divide

OpenStudy (anonymous):

If you need 10 mg of a drug and multiply with 0.4 mg/mL, you get some nonsense. If you divide 10 mg with 0.4 mg/ml, you will get a volume...

OpenStudy (anonymous):

i just dont understand.

OpenStudy (anonymous):

(10 mg) / 0.4 mg/mL) = 25 mL

OpenStudy (anonymous):

And so, if you know the volume of a teaspoon, you can get the amount of teaspoons that is.

OpenStudy (anonymous):

is the answer 5?

OpenStudy (anonymous):

Indeed, (25 ml) / (5 ml/teaspooon) = 5 teaspoons

OpenStudy (anonymous):

Note that "/" means "per".

OpenStudy (anonymous):

Or "for each"
