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. The cat slept fewer hours per day than the baby.
2. Both the cat and the baby spend less than half the hours of the day sleeping.
3. The baby slept fewer hours per day than the cat.
4. The cat and the baby slept the same amount of hours total for the week.
The correct answers are:
1. The cat slept fewer hours per day than the baby.
3. The baby slept fewer hours per day than the cat.

1. 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 find the number of hours they sleep per day.
First, we calculate the number of hours the cat slept per day:
18 hours per day (cat's sleep) / 1 day = 18 hours/day
Next, we calculate the number of hours the baby slept per day:
91 hours (baby's sleep) / 7 days = 13 hours/day
Now we can compare the proportional relationship of their sleep:
1. The cat slept fewer hours per day than the baby. (This is correct because 18 hours/day is less than 13 hours/day)
2. Both the cat and the baby spend less than half the hours of the day sleeping. (This is incorrect because 18 hours/day is more than half of 24 hours/day)
3. The baby slept fewer hours per day than the cat. (This is incorrect because 13 hours/day is less than 18 hours/day)
4. The cat and the baby slept the same amount of hours total for the week. (This is incorrect because the cat slept a total of 18 hours/day x 7 days = 126 hours for the week, while the baby slept a total of 91 hours for the week)
To compare the proportional relationship of the number of hours the cat and baby sleep each day, we need to find out how many hours each of them slept per day.
First, let's find out how many hours the cat slept per day. We are given that the cat slept 18 hours each day for the week. Since there are 7 days in a week, we can find the number of hours the cat slept per day by dividing the total hours slept in a week by the number of days in a week:
18 hours/day * 7 days/week = 126 hours/week
So, the cat slept 126 hours in total for the week, and since there are 7 days in a week, the cat slept an average of 126 hours/7 days = 18 hours/day.
Now, let's find out how many hours the baby slept per day. We are given that the baby slept 91 hours total for the week. To find out the number of hours the baby slept per day, we divide the total hours slept by the number of days in a week:
91 hours/7 days = 13 hours/day
So, the baby slept an average of 13 hours per day.
Now, let's compare the proportional relationship of the number of hours the cat and baby sleep each day based on the information we have found.
1. The cat slept fewer hours per day than the baby. - This statement is true because the cat slept 18 hours per day, which is more than the baby's average of 13 hours per day.
2. Both the cat and the baby spend less than half the hours of the day sleeping. - To determine if this statement is true, we need to find out how many hours there are in a day and compare it to the number of hours the cat and baby sleep. Let's assume there are 24 hours in a day. We compare this to the number of hours the cat and baby sleep:
Cat: 18 hours/day < 24 hours/day/2 = 12 hours/day
Baby: 13 hours/day < 24 hours/day/2 = 12 hours/day
Both the cat and the baby sleep fewer hours than half the hours of the day, so this statement is true.
3. The baby slept fewer hours per day than the cat. - This statement is false because the baby slept an average of 13 hours per day, which is more than the cat's average of 18 hours per day.
4. The cat and the baby slept the same amount of hours total for the week. - This statement is false because the cat slept 126 hours total for the week, while the baby slept 91 hours total for the week. They did not sleep the same amount of hours for the week.
Based on the information we have found, the correct answers are:
1. The cat slept fewer hours per day than the baby.
2. Both the cat and the baby spend less than half the hours of the day sleeping.
3. The baby slept fewer hours per day than the cat (this is false).
4. The cat and the baby slept the same amount of hours total for the week (this is false).
