When solving any problem, first check that the order and the supply are in the same weight measure. In this problem, no equivalent is necessary. Estimate the amount to give. Formula Method: 150 mg/15 mg * 1 mL = 150/15 = 10 mL. Proportion (Ratios): 1 mL : 15 mg :: x mL : 150 mg; 15x = 150/15 = 10 mL. Proportion (Fractions): 1 mL/15 mg = x mL/150 mg; 15x = 150/15 = 10 mL. Dimensional Analysis: 1 mL/15 mg * 150 mg = 150 *1/15 = 10 mL. For liquids, the four methods are set up just as for oral solids, except the supply includes a liquid measurement.
