Last week, Malka'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 (f point)
Both the cat and the baby spend less than hat the hours of the day sleeping
O The cat slept fewer hours per day than the baby
O The baby slept fewer hours per day than the cat
O The cat and the baby slept the same amount of hours total for the week
The correct answer is:
O 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 they sleep per day.
Step 1: Calculate the total number of hours the cat slept for the week
The cat slept 18 hours each day, so to find the total for the week, we can multiply 18 by 7 (number of days in a week).
Total cat's sleep hours = 18 hours/day x 7 days/week = 126 hours/week
Step 2: Calculate the average number of hours the cat slept per day
To find the average number of hours the cat slept per day, we divide the total cat's sleep hours by the number of days in the week.
Average cat's sleep hours = 126 hours/week ÷ 7 days/week = 18 hours/day
Step 3: Calculate the average number of hours the baby slept per day
To find the average number of hours the baby slept per day, we divide the total baby's sleep hours by the number of days in the week.
Average baby's sleep hours = 91 hours/week ÷ 7 days/week = 13 hours/day
Now, let's compare the proportional relationship of the number of hours the cat and baby sleep each day.
The cat slept an average of 18 hours per day, while the baby slept an average of 13 hours per day. Therefore, the correct answer is:
The cat slept fewer hours per day than the baby. (Option O: The baby slept fewer hours per day than the cat)
To compare the proportional relationship between the number of hours the cat and the baby sleep each day, we need to calculate the average number of hours they sleep per day.
The cat slept 18 hours each day. Therefore, the cat slept a total of 18 hours * 7 days = 126 hours for the week.
The baby slept a total of 91 hours for the week.
To calculate the average number of hours they sleep per day, we divide the total number of hours by the number of days:
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, we can conclude that the cat slept more hours per day (18) than the baby (13). Thus, the correct answer is:
- O The cat slept fewer hours per day than the baby.
