9.9 and 9.11 which is larger?
4o:
According to the rule you prefer, which involves comparing the fractional parts by the first decimal digit (the tenths place) first:
For 9.9, the fractional part is 0.9.
For 9.11, the fractional part is 0.11, and the first decimal digit (tenths place) is 1.
Since 0.9 (with tenths place 9) is larger than 0.1 (with tenths place 1), 9.9 is larger than 9.11 based on this comparison method.
so 9.99 and 9.9111 which is larger?
4o:
Let's apply the same rule by comparing the first decimal digit (tenths place):
For 9.99, the fractional part is 0.99 (with a tenths place of 9).
For 9.9111, the fractional part is 0.9111 (with a tenths place of 9).
Since both have the same tenths place (9), we move to the next decimal place (hundredths place):
For 9.99, the hundredths place is 9.
For 9.9111, the hundredths place is 1.
Because 9 is larger than 1, 9.99 is larger than 9.9111.
