To compare the two numbers, we start by looking at the tenths place.
For the number 3.45, the tenths place is 4.
For the number 3.4, the tenths place is 4.
Since their tenths places are the same, we move on to the hundredths place.
For 3.45, the hundredths place is 5.
For 3.4, there is no digit in the hundredths place, which can be considered as 0.
Now we compare the hundredths place:
- 5 (in 3.45) is greater than 0 (in 3.4).
Thus, 3.4 is less than 3.45.
The order from least to greatest is:
3.4, 3.45
So the smallest number is:
3.4
