Same as ordering fractions: 2/17, 1/9, 3/29, 12/101, 7/66.
An easy way is to invert all the fractions:
17/2=8.5; 9/1=9.0; 29/3=9.7; 101/12=8.4; 66/7=9.4 to one place of decimals.
Now order them greatest to least:
9.7, 9.4, 9.0, 8.5, 8.4.
The corresponding fractions will now be in the correct order (least to greatest):
3 to 29, 7:66, 1/9, 2:17, 12/101.
