Last week, Malika's cat sleeps 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.
A.The cat and the baby slept the same amount of hours total for the week.
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 baby slept fewer hours per day than the cat.
To compare the proportional relationship of the number of hours the cat and the baby sleep each day, we need to find the number of hours each of them sleeps per day.
The cat sleeps 18 hours each day (assuming it's consistent throughout the week).
The baby slept 91 hours total for the week. To find the number of hours the baby sleeps per day, we divide 91 by 7 (number of days in a week): 91 / 7 = 13.
So, the baby slept approximately 13 hours each day.
Comparing the numbers, we can see that the cat slept more hours per day than the baby.
Therefore, the 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 average number of hours each one slept per day.
The cat slept a total of 18 hours each day for the week.
To find the average number of hours the cat slept per day, we can divide the total number of hours the cat slept (18) by the number of days in the week (7).
Average number of hours the cat slept per day = 18 hours / 7 days = 2.57 hours.
The baby slept a total of 91 hours for the week.
To find the average number of hours the baby slept per day, we can divide the total number of hours the baby slept (91) by the number of days in the week (7).
Average number of hours the baby slept per day = 91 hours / 7 days = 13 hours.
Comparing the averages, we can see that the baby slept more hours per day than the cat, so the answer is:
C. The cat slept fewer hours per day than the baby.
To compare the proportional relationship between the number of hours the cat and baby sleep each day, we need to calculate the average number of hours per day for each of them.
To find the average number of hours the cat sleeps each day, we divide the total number of hours slept by the cat in a week (which is 18 hours per day) by 7 (number of days in a week):
Average hours per day for the cat = 18 hours / 7 days = 2.5714 (approximately)
To find the average number of hours the baby sleeps each day, we divide the total number of hours slept by the baby in a week (which is 91 hours total) by 7 (number of days in a week):
Average hours per day for the baby = 91 hours / 7 days = 13
Now we can compare the proportional relationship:
A. The cat and the baby slept the same amount of hours total for the week.
Based on our calculations, the cat slept 18 hours per day on average, while the baby slept 13 hours per day on average. Therefore, option A is incorrect.
B. Both the cat and the baby spend less than half the hours of the day sleeping.
Half the hours of the day is 12 hours. The cat sleeps more than 12 hours on average, so option B is incorrect.
C. The cat slept fewer hours per day than the baby.
Based on our calculations, the cat slept 2.5714 (approximately) hours per day on average, while the baby slept 13 hours per day on average. Therefore, option C is incorrect.
D. The baby slept fewer hours per day than the cat.
Based on our calculations, the cat slept 2.5714 (approximately) hours per day on average, while the baby slept 13 hours per day on average. Therefore, option D is correct.
So, the correct answer is: D. The baby slept fewer hours per day than the cat.
