Express 75 micrograms (mcg) in milligrams.
Answer and explanation
Correct answer: A. 0.075 mg
- Step 1: 1,000 mcg make 1 mg. Step 2. 75 / 1,000 = 0.075 mg. Answer: 0.075 mg. Why not the others: 75000 mg: the value was multiplied instead of divided. 0.75 mg: 1 mg was treated as 100 mcg. 0.007 mg: an extra factor of 10 was applied.
