Answer 1

To determine which serving size has a different ratio of serving size to pounds of meat, let's calculate the ratio for each serving size:

1. 30 servings:

   • Ratio = 30 / 2 = 15

2. 75 servings:

   • Ratio = 75 / 6 = 12.5

3. 120 servings:

   • Ratio = 120 / 8 = 15

4. 180 servings:

   • Ratio = 180 / 12 = 15

Now, comparing the ratios:

• 30 servings: 15
• 75 servings: 12.5
• 120 servings: 15
• 180 servings: 15

The ratio for 75 servings is different from the others. Therefore, the employee made an error in the calculation for the 75 servings.
