Answer:
Child's dosage=60 milligram
Step-by-step explanation:
The correct formula is below
C= a/(a+12) ∙ A
Where,
C = child’s dosage in milligrams
a = age of the child
A = adult dosage in milligrams
a=6 year old
A=180 milligrams
C= a/(a+12) ∙ A
=6/(6+12)*180
=6/18*180
=1/3*180
=60
Child's dosage in milligram=60 milligram
