List the following numbers in order from least (top) to greatest (bottom).

19\2
√16
8
√80
9.4

√16 = 4

19/2 = 9.5
√80 = 8.944
8
9.4

In order from least to greatest:
4
9.5
8
8.944
9.4

To list the given numbers in order from least to greatest, let's analyze each number step by step:

First, simplify the numbers:

√16 = 4 (square root of 16 is 4)
√80 = √(16 * 5) = 4 * √5 ≈ 8.94 (approximated to two decimal places)

Now the simplified numbers are:
19/2 = 9.5
4
8
8.94 (approximated from √80)
9.4

Arranging them in ascending order, from least to greatest:
4
8
8.94
9.4
9.5

So, the numbers in order from least to greatest are:
4, 8, 8.94, 9.4, 9.5
