Let's analyze the information provided.
-
Cat's sleeping hours:
- The cat sleeps 18 hours each day.
- For one week (7 days), the total sleep for the cat is: \[ 18 , \text{hours/day} \times 7 , \text{days} = 126 , \text{hours} \]
-
Baby's sleeping hours:
- The baby sleeps a total of 91 hours for the week.
Now let's compare their daily sleeping hours:
- The cat sleeps 18 hours per day.
- To find the average daily sleep for the baby, we would divide the total weekly sleep by 7: \[ 91 , \text{hours} \div 7 , \text{days} \approx 13 , \text{hours/day} \]
Now we can evaluate the responses:
-
The cat and the baby slept the same amount of hours total for the week.
- This is false (126 hours for the cat vs 91 hours for the baby).
-
The cat slept fewer hours per day than the baby.
- This is false (18 hours for the cat vs approximately 13 hours for the baby).
-
The baby slept fewer hours per day than the cat.
- This is true (13 hours for the baby vs 18 hours for the cat).
-
Both the cat and the baby spend less than half the hours of the day sleeping.
- There are 24 hours in a day, half would be 12 hours.
- The cat sleeps 18 hours (more than half), and the baby sleeps approximately 13 hours (more than half).
Taking everything into account, the only accurate comparison is:
The baby slept fewer hours per day than the cat.
