Question

a patient needs to take 85% of a 200 g medication dose. how much medication should the patient take?
170 g
125 g
4.25 g
400 g

Explanation:

Step1: Convert percentage to decimal

To find 85% of 200 g, first convert 85% to a decimal. We know that to convert a percentage to a decimal, we divide by 100. So, \( 85\% = \frac{85}{100}= 0.85 \).

Step2: Multiply by the total dose

Now, multiply this decimal by the total medication dose (200 g) to find the amount the patient should take. The formula is \( \text{Amount} = \text{Percentage (decimal)} \times \text{Total Dose} \). Substituting the values, we get \( 0.85\times200 \). Calculating this, \( 0.85\times200 = 170 \) g.

Answer:

170 g
