Answer:
D
Step-by-step explanation:
Convert all units to one form (decimal, fraction, or percentage)
I will convert them all into decimals since 2 of the 4 numbers are already decimals:
-1/3
Divide -1 by 3 to convert the fraction into a decimal
-1/3 = -0.333333 repeating
-66%
Move the decimal place two places to the left to convert the percentage into a decimal
-66% = -0.66
Now compare:
-0.66. -0.33. -0.45. 1.8
The only positive number is 1.8 so that is the greatest.
-0.66 is the largest negative number so that is the smallest.
We must place them in order from greatest to least:
1.8, -0.33, -0.45, -0.66
Convert them back to their original numbers:
1.8, -1/3, -0.45, -66%
