Maximum number of pizzas made by 4.5 pounds of floor = 6
Explanation:
Quantity of floor Carlos has = 4.5 pounds
![\text{Part of floor needed by Carlos to make 1 pizza = }(3)/(4)](https://img.qammunity.org/2019/formulas/mathematics/high-school/psbjfhjm781wvrb6bc0dsg6up25wcqzxpc.png)
![\text{So, 1 pound of floor can make }(4)/(3)\text{ pizza}](https://img.qammunity.org/2019/formulas/mathematics/high-school/mn481berylohp5cbncq5riketj1u3ufdeb.png)
We need to find maximum number of pizzas made by 4.5 pounds of floor
![\text{So, 4.5 pounds of floor can make }(4)/(3)* 4.5\text{ pizza}](https://img.qammunity.org/2019/formulas/mathematics/high-school/3at7v6p8rjoxbdm9wq32ykdjw8afx3s3pm.png)
![\text{So, 4.5 pounds of floor can make }6\text{ pizzas}](https://img.qammunity.org/2019/formulas/mathematics/high-school/1jpp8qdrmh0dyuacncqc7uqgcvphpb8vaa.png)
Therefore, Maximum number of pizzas made by 4.5 pounds of floor = 6
