<u>I'm assuming you're formula is "</u><span><u>C=a/(a+12)*A" as that is only logical</u></span><span>
You get the formula </span><u>"C=a/(a+12)*A"
</u>You insert the numbers given, in place of the letters given. <u> </u>C=6/(6+12)*180 <u />C=3*180 C=540 mg
Which is of course wrong because it is more than the adults dosage. What i'm trying to say is "Your formula is incorrect , follow the steps I gave, but use the correct formula"
