Roberto needs 5.4 kg of clay more than the weight of the three pieces
to finish his project
Step-by-step explanation:
The given is:
1. Roberto needs 10 kilograms of clay for a ceramics project
2. He already has three pieces that weigh 1.3 kg, 2.4 kg, and 0.9 kg
We need to find how much more clay he needs
At first lets add the weight of the three pieces
∵ The first piece weigh 1.3 kg
∵ The second piece weigh 2.4 kg
∵ The third piece weigh 0.9 kg
∴ The weight of them = 1.3 + 2.4 + 0.9
∴ The weight of them = 4.6 kg
∵ He needs 10 kilograms to finish his project
- Subtract the sum of the three pieces from 10
∴ He needs = 10 - 4.6
∴ He needs = 5.4 kg
Roberto needs 5.4 kg of clay more than the weight of the three
pieces to finish his project
