2025年1月31。DS回答1.9和1.11,谁大?Yes, 1.9 is smaller than 1.11. When comparing decimal numbers, you look at each digit from left to right. Here, both numbers have "1" in the units place, but in the tenths place, 1.9 has a "9" while 1.11 has a "1". Since 9 is greater than 1, it might seem confusing, but 1.11 actually has an additional hundredths place (the second "1"), making it larger than 1.9. So, 1.9 < 1.11.
