A horse is prescribed 128 mg liquid for a fever. However the oral solution is at a dose of 160mg/5mL. How many mL should the horse receive?

The horse should receive 4 mL

Step-by-step explanation:

Step 1: Find the mL of oral solution the horse should be given.

Prescribed amount = 128 mg

Amount of solution in 160 mg = 5 mL

Amount of solution in 1 mg = 5/160 mL

⇒ Amount of solution in 128 mg = 128 * 5/160 = 4 mL
