Place the following in ordered from least to greatest:
3/5, 9/12, 6/8, 5/6

convert to common denominator and compare

You need to get common denominators so that you can relate each fraction to the other ones.
Another way would be to write each as a decimal.
The first 3/5 = .6 
true. also, u can reduce each fraction to find common denominator faster and less messily
