The correct Answer is:
To find the percentage of gold in 14 carat gold, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Definition of Carat**: - Carat is a measure of the purity of gold. Pure gold is defined as 24 carats. Therefore, 14 carat gold means that out of 24 parts, 14 parts are pure gold. 2. **Calculate the Percentage of Gold**: - To find the percentage of gold in 14 carat gold, we use the formula: \[ \text{Percentage of Gold} = \left( \frac{\text{Number of Carats of Gold}}{\text{Total Carats}} \right) \times 100 \] - Plugging in the values for 14 carat gold: \[ \text{Percentage of Gold} = \left( \frac{14}{24} \right) \times 100 \] 3. **Perform the Calculation**: - First, calculate \( \frac{14}{24} \): \[ \frac{14}{24} = 0.5833 \] - Now, multiply by 100 to convert it to a percentage: \[ 0.5833 \times 100 = 58.33\% \] 4. **Round the Result**: - The percentage of gold in 14 carat gold can be approximated to 58%. 5. **Conclusion**: - Therefore, the percentage of gold in 14 carat gold is approximately 58%. ### Final Answer: The percentage of gold in 14 carat gold is **58%**. ---
