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: 300 mg/250 mg * 5 mL = 1500/250 = 6 mL. Proportion (Ratios): 5 mL : 250 mg :: x mL : 300 mg; 250x = 1500/250 = 6 mL. Proportion (Fractions): 5 mL/250 mg = x mL/300 mg; 250x = 1500/250 = 6 mL. Dimensional Analysis: 5 mL/250 mg*300 mg = 1500/250 = 6 mL.
