Last week, Malika's cat slept 18 hours each day. Her baby slept 91 hours total for the week. Compare the proportional relationship of the number of hours the cat and baby sleep each day. (1 point)
A. The baby slept fewer hours per day than the cat.
B. Both the cat and the baby spend less than half the hours of the day sleeping.
C. The cat slept fewer hours per day than the baby.
D. The cat and the baby slept the same amount of hours total for the week
The correct answer is C. The cat slept fewer hours per day than the baby. Since the cat slept 18 hours per day and the baby slept a total of 91 hours for the week, the baby slept more hours per day on average.
To compare the proportional relationship of the number of hours the cat and baby sleep each day, we can calculate the average number of hours they sleep per day.
The cat slept 18 hours each day, and there are 7 days in a week. So, the total number of hours the cat slept for the week is 18 * 7 = 126 hours.
The baby slept a total of 91 hours for the week.
To find the average number of hours each day, we divide the total hours by 7 (the number of days in a week).
For the cat: 126 hours / 7 days = 18 hours per day
For the baby: 91 hours / 7 days = 13 hours per day
Comparing the averages:
A. The baby slept fewer hours per day than the cat. (This is false because the baby slept 13 hours per day, while the cat slept 18 hours per day.)
B. Both the cat and the baby spend less than half the hours of the day sleeping. (This is false because the cat sleeps for 18 hours, which is more than half of the day, and the baby slept for 13 hours, which is also more than half of the day.)
C. The cat slept fewer hours per day than the baby. (This is true because the baby slept for 13 hours per day, while the cat slept for 18 hours per day.)
D. The cat and the baby slept the same amount of hours total for the week. (This is false because the cat slept for 126 hours, while the baby slept for 91 hours.)
Therefore, the correct answer is: C. The cat slept fewer hours per day than the baby.
To compare the proportional relationship of the number of hours the cat and baby sleep each day, we need to calculate the number of hours each one slept per day.
The cat slept 18 hours each day for a week. To find the number of hours the cat slept in one day, we divide 18 by 7 (the number of days in a week):
18 / 7 = 2.57 or approximately 2.6 hours per day.
The baby slept a total of 91 hours for the week. To find the number of hours the baby slept per day, we divide 91 by 7:
91 / 7 = 13 hours per day.
Comparing the results, we see that the baby slept more hours per day (approximately 13 hours) compared to the cat's 2.6 hours. Therefore, the correct answer is:
C. The cat slept fewer hours per day than the baby.
