To order these, you need to find the lowest common denominator, which is 64. Now you need to make all them have the same denominator.
1/2 = 32/64
5/16 = 20/64
30/64 = 30/64
3/8 = 24/64
9/32 = 18/64
Now just look at the second column and look at the top(first) number to order them.
The order from least to greatest:
9/32, 5/16, 3/8, 30/64, 1/2
