To find the day when the animals were fed the least amount of food, we need to calculate the total amount of food fed to the animals for each day.
- **Friday:**
- Cats: 6.5 pounds
- Dogs: 8.45 pounds
- Rabbits: 1.2 pounds
- Total = 6.5 + 8.45 + 1.2 = **16.15 pounds**
- **Saturday:**
- Cats: 8.875 pounds
- Dogs: 4.625 pounds
- Rabbits: 2.4 pounds
- Total = 8.875 + 4.625 + 2.4 = **16.9 pounds**
- **Sunday:**
- Cats: 4.1 pounds
- Dogs: 3.2 pounds
- Rabbits: 2.125 pounds
- Total = 4.1 + 3.2 + 2.125 = **9.425 pounds**
- **Monday:**
- Cats: 6.25 pounds
- Dogs: (not provided)
- Rabbits: 2.125 pounds
- Total = 6.25 + 0 + 2.125 = **8.375 pounds** (assuming no food was provided for dogs as it is missing)
Now, comparing the totals:
- Friday: 16.15 pounds
- Saturday: 16.9 pounds
- Sunday: 9.425 pounds
- Monday: 8.375 pounds
The day when the animals were fed the least food is **Monday**.
