Ok, so IDK if I'm about to do this problem right, but here we go;
so first, lets change these all to decimals (I more of a decimal gal)
3 1/2 = 3.5
3 2/3 = 3.6666 (repeating)
3 3/5 = 3.6
3 3/8 = 3.375
So now, just order them from greatest to least.
3.66666, 3.6, 3.5, 3.375.
Now, change them back to fractions.
3 2/3, 3 3/5, 3 1/2, 3 3/8
So, if I'm correct, the answer is 3 2/3%, 3 3/5%, 3 1/2%, 3 3/8%
Hopefully I solved your problem!
