This is worth 20 points if you don't believe me look down below pls do the work below put them in order from least to greatst

0.5,2/3,-3/4,1.2,2.3

Well first I'd turn them all into decimals meaning the numbers would be: 
-0.75, 0.5, 0.6 repeating (basically the decimal doesn't end ex. 0.66666...), -2.3 repeating, and 1.2.

So the order would be -7/3, -3/4, 0.5, 2/3, and 1.2.

Hope this helped!
