Answer:-
Explanation:
To order the numbers from least to greatest, you need to convert the percentages to decimal form (percentages are out of 100) and then arrange the numbers:
1. Convert 2% to a decimal by dividing by 100:
2% = 2/100 = 0.02
Now you have the numbers in decimal form: -1/2, 0.02, 2.1, and 0.20.
2. Order them from least to greatest:
-1/2 < 0.02 < 0.20 < 2.1
So, the ordered numbers are: -1/2, 0.02, 0.20, 2.1.
