Write each of the fractions in their decimal form and then arrange them from the smallest to the biggest.

31/50
67/100

Jen,
It's quickest to change them all into decimals, and then arrange them:
2/3=.67 repeating (.666666etc7)
3/5=.6
31/50=.62
67/100=.67

Kathleen,
Is this right? smallest to biggest
0.62 31/50
0.67 2/3
0.67 67/100
0.6 3/5

MathMate,
The conversion are basically correct, but the ordering is not correct. However, the fractions are quite close, so if you could keep one more decimal place in the decimal numbers, you can compare and order them correctly.
Hint: write 3/5=0.6 as 0.600,
31/50=0.620, 67/100=0.670, ...
