To find the weight of Gabriel's pumpkin, we need to add the weight of Marcos' pumpkin to the additional weight Gabriel's pumpkin has.
Marcos' pumpkin weighs 1.37 pounds. Gabriel's pumpkin weighs 0.24 pounds more than Marcos' pumpkin:
Gabriel's pumpkin weight = Marcos' pumpkin weight + additional weight Gabriel's pumpkin weight = 1.37 pounds + 0.24 pounds
Now, we can perform the addition:
1.37 + 0.24 = 1.61 pounds
So, Gabriel's pumpkin weighs 1.61 pounds.
The correct response is 1.61.
