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.
Responses
The cat slept fewer hours per day than the baby
Both the cat and the baby spend less than half the hours of the day sleeping
The baby slept fewer hours per day than the cat.
The cat and the baby slept the same amount of hours total for the week.
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 calculate the average number of hours they slept per day.
The cat slept 18 hours each day, so in a week, the cat slept 18 hours * 7 days = 126 hours.
The baby slept 91 hours for the week, divided by 7 days gives us an average of 91 hours / 7 days = 13 hours per day.
Comparing the average number of hours per day, we can see that the baby slept fewer hours per day than the cat. Therefore, the correct response is:
The baby slept fewer hours per day than the cat.
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 of them slept per day.
Given that the cat slept 18 hours each day for the week, we can calculate the total number of hours the cat slept using the formula:
Total hours cat slept = Cat's daily sleeping hours * Number of days in the week
= 18 hours/day * 7 days
= 126 hours
On the other hand, we are given that the baby slept a total of 91 hours for the week. To calculate the number of hours the baby slept per day, we divide the total hours by the number of days in the week:
Baby's sleeping hours per day = Total hours baby slept / Number of days in the week
= 91 hours/7 days
≈ 13 hours per day
Now, we can compare the proportional relationship between the cat and baby's sleeping hours per day.
Since the cat slept 18 hours per day and the baby only slept approximately 13 hours per day, we can conclude that the cat slept more hours per day than the baby. Therefore, the correct response is "The cat slept more hours per day than the baby."
