Answer: -2.1, -0.5, 5/100, 0.5, √5
Explanation:
Start with the negative numbers. Take the absolute value - the ones with the largest absolute value are the farthest from 0, so they are the smallest numbers.
-2.1, -0.5
Then, convert the numbers not in decimals to decimals.
5/100 = 0.05
√5 is about 2.3.
5/100, 0.5, √5
