Answer:
There were 48 ounces of milk left
Explanation:
∵ Lessils used 25% of half a gallon of milk
→ Assume that the total amount of the milk is 25%
∴ The amount of milk left = 100% - 25% = 75%
∵ Half gallon = 64 ounces
→ That means the amount of milk left is 75% of 64 ounces
∴ The amount of milk left = 75% × 64
→ Divide 75% by 100 to change it to decimal
∵ 75% = 75 ÷ 100 = 0.75
∴ The amount of milk left = 0.75 × 64
∴ The amount of milk left = 48 ounces
∴ There were 48 ounces of milk left
