question 6 (2.5 points)
a construction project uses 50 bricks to build a 2 - meter wall for a medical clinic. write the comparison as a ratio in simplest form using a colon.
5:1
50:2
25:2
25:1

Explanation:

First Question (Medical Coder Claims)

Step1: Convert percentage to decimal

To find 5% of 200, first convert 5% to a decimal. 5% is equal to $0.05$.

Step2: Multiply total claims by decimal

Multiply the total number of claims (200) by the decimal form of the percentage ($0.05$). So, $200\times0.05 = 10$.

Step1: Identify the two quantities

The two quantities are the number of bricks (50) and the length of the wall (2 meters). The ratio is bricks : meters, so initially it's $50:2$.

Step2: Simplify the ratio

To simplify the ratio $50:2$, divide both parts by their greatest common divisor, which is 2. $\frac{50}{2}:\frac{2}{2}=25:1$.

Answer:

B. 10 claims
