. Cora says 4 + 0.05 has the same quotient as 40 + 5. How do you respond to him Sample answer: If 4 changes to 40, then 0.05 needs to change to 0.5, not 5. These two expressions will not have the same quotient

. A restaurant has 3 pounds of carrots to use on the salads they make. Their recipe calls for 0.5 pound of carrots for each salad The restaurant makes 10 salads. Will the restaurant have enough carrots to make this number of salads or will they run out Explain your answer
