Compare Decimal Numbers: Finding the Symbol Between 101.0 and 102.1

Question

Fill in the missing sign:

$101.0\text{ }_{—\text{ }}102.1$

Let's compare the numbers in the following way:

We notice that before the decimal point, both numbers start with 1 and then 0

After that, the numbers are different, 1 versus 2

Since 2 is greater than 1, the appropriate sign is:

$101.0 < 102.1$
