If a formula calls for 1 1/2 teaspoons per gallon, how many teaspoons are required for 5 gallons?

Explanation:
Scaling up involves multiplying the amount per unit by the number of units. Here, you need 1 1/2 teaspoons for each gallon, and you have 5 gallons. Multiply: 1 1/2 × 5 = (3/2) × 5 = 15/2 = 7 1/2. So you need 7 1/2 teaspoons in total (which is the same as 7.5 teaspoons).
