So before I tell you the answer this is a bit of explanation:)
To make it easier change the fraction into decimals!
3/8 = .375
5/16 =.3125
7/12 = .583
.5 = 0.5
.25 = 0.25
So, according to my calculations I believe it goes like this: 0.25, 0.375, 0.3125, 0.5, .583
Really I am not sure if this is correct but I hope this helps you understand you can order it whatever way you want but make sure you understand the explanation :) have a great day!!
