francis has 11 bottles containing 8 ounces of water each. he multiplies to determine that he has 88 ounces of water total. which addition equation could he use to check his answer? 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 = 88 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 = 64 8 + 11 = 19
Answer
Explanation:
Step1: Understand the problem
Francis has 11 bottles, each with 8 ounces of water. To check the total (88 ounces), we can represent the total as the sum of 11 eights.
Step2: Analyze each option
- Option 1: (8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8) (11 eights) sums to (8\times11 = 88).
- Option 2: The sum here is of 8 eights, (8\times8 = 64), not 88.
- Option 3: (8 + 11 = 19) is incorrect as it's adding the number of bottles and ounces per bottle, not the total ounces.
