During gym class, Alexis played dodgeball for 3/4 hour. After that, she played basketball for 1/4 hour. Which model represents how much more time was spent playing dodgeball than playing basketball?
1) 3/4 + 1/4 = 4/4
2) 3/4 + 1/4 = 3 1/4 + 4/4
3) 3/4 – 1/4 = 2/4
4) 3/4 – 1/4 = 4/4

The correct answer is 3) 3/4 – 1/4 = 2/4.
Explanation:
To find out how much more time Alexis spent playing dodgeball than basketball, you subtract the time spent on basketball from the time spent on dodgeball.
So, you calculate:
3/4 (dodgeball) – 1/4 (basketball) = 2/4.
This shows that Alexis spent 2/4 hour more playing dodgeball than basketball.
