To compare the proportional relationship of the number of hours the cat and baby sleep each day, we need to find the average number of hours they sleep each day.
The cat sleeps 18 hours each day.
To find the average number of hours the cat sleeps each day, we divide the total number of hours the cat sleeps in a week (18 hours/day x 7 days/week) by the number of days in a week (7 days):
18 hours/day x 7 days/week = 126 hours/week
126 hours/week ÷ 7 days/week = 18 hours/day
The baby sleeps 91 hours total for the week.
To find the average number of hours the baby sleeps each day, we divide the total number of hours the baby sleeps in a week (91 hours) by the number of days in a week (7 days):
91 hours ÷ 7 days/week = 13 hours/day
Comparing the averages, we find that the cat sleeps 18 hours each day while the baby sleeps 13 hours each day.
Thus, the proportional relationship is that the cat sleeps 18/13 hours for each hour the baby sleeps.
Last week, Malika’s cat sleeps 18 hours each day. Her baby sleeps 91 hours total for the week. Compare the proportional relationship of the number of hours the cat and baby sleep each day.
