List the numbers from least to greatest. When approximating an irrational number, round to the nearest tenth.
5 squared, 3.7, 1/2, -4, -9/4
-4, -2.2, 0.5, 3.7, 25
To list the numbers from least to greatest, we need to arrange them in ascending order:
-9/4, -4, 1/2, 3.7, 5^2
When approximating an irrational number, like 5 squared, we will round it to the nearest tenth. The square of 5 is 25, and when rounded to the nearest tenth, it remains 25.
So, the final list is:
-9/4, -4, 1/2, 3.7, 25.
