Question

A medication was reduced from 500 mg to 400mg, what is the precent decrease?

Answer 1

To determine the percent decrease of medication from 500 mg to 400 mg, subtract the new amount from the original, divide by the original amount, and multiply by 100, resulting in a 20% decrease.

Step-by-step explanation:

To calculate the percent decrease from 500 mg to 400 mg, you first find the difference between the two amounts. This difference is 500 mg - 400 mg = 100 mg. Then, you divide the difference by the original amount (500 mg in this case) and multiply by 100 to find the percentage. So the calculation would be (100 mg / 500 mg) × 100, which equals 20%. Therefore, the percent decrease in medication from 500 mg to 400 mg is 20%.
