anonymous · Answer

It gives you the information baby weight-3.1kg, dose of medication-31mg
and it asks for mg/kg, 
1.) Find mg dosage
      
         31mg *  1mg      Cross Multiply
        1kg       3.1kg 

         31mg*3.1kg= 96.1mg

        Dosage Rate = 3.1kg/96.1mg safe dosage for infant 
         For a 3.1kg infant a safe dosage of Antibiotics is 96.1mg
