?Prompt
Is 9.11 greater than 9.9?
Response
To determine whether 9.11 is greater than 9.9, we need to compare the two decimal numbers carefully.
Step 1: Align the Numbers
To make the comparison clear, we can express both numbers with the same number of decimal places:
- 9.11 (already has two decimal places)
- 9.9 → 9.90 (adding a zero to match decimal places)
Now we have:
9.11
9.90
Step 2: Compare Digit by Digit
Start from the leftmost digit and move right:
- Units place: Both numbers have 9 → equal.
- Tenths place: 1 vs 9 → 9 > 1
Since 9 > 1 in the tenths place, we can conclude that 9.90 > 9.11, and thus 9.9 > 9.11.
Step 3: Alternative Verification (Optional)
To double-check, we can:
- Multiply both numbers by 100 to eliminate decimals:
- 9.11 × 100 = 911
- 9.9 × 100 = 990
Now compare the integers: 990 > 911, confirming that 9.9 > 9.11.
Final Conclusion
Since 9.9 > 9.11, the statement "Is 9.11 greater than 9.9?" is false.
$$ \boxed{No} $$
