Final answer:
The friends spend the same amount of time on each activity.
Step-by-step explanation:
The friends spend 1/3 hour collecting sticks and 5/6 hour building a fort. To determine if they spend the same amount of time on each, we can compare the fractions to see if they are equivalent. We can do this by finding a common denominator. The least common multiple of 3 and 6 is 6.
Converting the first fraction, we get 2/6 hour spent collecting sticks. Converting the second fraction, we get 5/6 hour spent building a fort. Since both fractions have the same denominator and are the same, they represent the same amount of time. Therefore, the friends spend the same amount of time on each activity.
