$$

Understanding the Problem

To find the percent equivalent to a fraction, we need to divide the numerator by the denominator and multiply the result by 100. In this case, we have the fraction $\frac{18}{30}$, and we want to find its equivalent percentage.

Simplifying the Fraction

Before we can find the percent equivalent, we need to simplify the fraction $\frac{18}{30}$. We can do this by dividing both the numerator and the denominator by their greatest common divisor (GCD). The GCD of 18 and 30 is 6.

import math

# Define the numerator and denominator
numerator = 18
denominator = 30

# Calculate the GCD
gcd = math.gcd(numerator, denominator)

# Simplify the fraction
simplified_numerator = numerator // gcd
simplified_denominator = denominator // gcd

print(f"Simplified fraction: {simplified_numerator}/{simplified_denominator}")

Calculating the Percent Equivalent

Now that we have the simplified fraction, we can find its percent equivalent. We do this by dividing the numerator by the denominator and multiplying the result by 100.

# Calculate the percent equivalent
percent_equivalent = (simplified_numerator / simplified_denominator) * 100

print(f"Percent equivalent: {percent_equivalent}%")

Evaluating the Answer Choices

Now that we have the percent equivalent, we can evaluate the answer choices to see which one matches our result.

Answer Choice	Value
A. 66%	66.0%
B. 56%	56.0%
C. 39%	39.0%
D. 60%	60.0%

Conclusion

Based on our calculations, the percent equivalent to $\frac{18}{30}$ is 60%. Therefore, the correct answer is D. 60%.

Additional Examples

Here are a few more examples of finding the percent equivalent to a fraction:

• $\frac{24}{40}$: Simplify the fraction to $\frac{3}{5}$, then calculate the percent equivalent: (3/5) * 100 = 60%
• $\frac{36}{60}$: Simplify the fraction to $\frac{3}{5}$, then calculate the percent equivalent: (3/5) * 100 = 60%
• $\frac{48}{80}$: Simplify the fraction to $\frac{3}{5}$, then calculate the percent equivalent: (3/5) * 100 = 60%

In each of these examples, the percent equivalent is 60%. This is because the simplified fraction is always $\frac{3}{5}$, and the percent equivalent of $\frac{3}{5}$ is always 60%.

Final Answer

The final answer is D. 60%.
