When solving any problem, first check that the order and the supply are in the same weight measure. For this problem, no equivalent is necessary. Estimate the amount to give. Formula Method: 40 mg/20 mg* 5 mL = 200/20 = 10 mL. Proportion (Ratios): 5 mL : 20 mg :: x mL : 40 mg; 20x = 200/20 = 10 mL. Proportion (Fractions): 5 mL/20 mg = x mL/40 mg; 20x = 200/20 = 10 mL. Dimensional Analysis: 5 mL/20 mg *40 mg = 5 mL * 40/20 = 200/20 = 10 mL. For liquids, the four calculation methods are set up the same as for oral solids, except the supply includes a liquid measurement.
