40 6
80 8
120 12
The employee who created the chart made an error when computing the number of pounds of meat for one of the serving sizes. For which serving size is the ratio of size to pounds of meat different from the other ratios?

To determine which serving size has a different ratio of serving size to pounds of meat, we can calculate the ratio for each serving size.

  • For 20 servings: \( \frac{20}{2} = 10 \)
  • For 40 servings: \( \frac{40}{6} \approx 6.67 \)
  • For 80 servings: \( \frac{80}{8} = 10 \)
  • For 120 servings: \( \frac{120}{12} = 10 \)

Now we compare the ratios:

  • 20 servings: 10
  • 40 servings: 6.67
  • 80 servings: 10
  • 120 servings: 10

The ratio for 40 servings is different from the other ratios.

Therefore, the answer is 40 servings.
