To find the mass of each item, we need to look at the balance scales. When the scale is balanced (level), it means the weight on the left side is equal to the weight on the right side. We can add up the numbers on the weights to find the total mass.
1. Watermelon:
* On the right side of the scale, there are two weights labeled
4 and
8.
* Add these numbers together: $4 + 8 = 12$.
* So, the watermelon weighs
12.
2. Pumpkin:
* On the right side of the scale, there are two weights labeled
6 and
2.
* Add these numbers together: $6 + 2 = 8$.
* So, the pumpkin weighs
8.
3. Lettuce:
* On the right side of the scale, there are two weights labeled
1 and
7.
* Add these numbers together: $1 + 7 = 8$.
* So, the lettuce weighs
8.
Final Answer:
Watermelon: 12
Pumpkin: 8
Lettuce: 8
