What will be an ideal response?
Answers will vary. Possible answer: When comparing two numbers in decimal notation, one should start at the left, not at the right, comparing corresponding digits moving left to right until a difference is found. If one starts at the left, the first difference is found in the hundredths place. Since 8 is larger than 7, the second number is larger.
