1. The problem asks: What fraction of Mel's dinners in April were fish dinners? 2. To find the fraction of fish dinners, we use the formula: $$\text{Fraction of fish dinners} = \frac{\text{Number of fish dinners}}{\text{Total number of dinners}}$$ 3. From the list, Mel has 5 dinner choices: chicken, pork, lamb, fish, and steak. 4. Assuming each choice is equally likely or equally counted, the total number of dinners is 5. 5. The number of fish dinners is 1 (since fish is one of the 5 choices). 6. Substitute these values into the formula: $$\frac{1}{5}$$ 7. Therefore, the fraction of fish dinners is $\frac{1}{5}$. This means fish dinners made up one-fifth of Mel's dinner choices in April.
