Ok so being in middle school I might not do this right but I will help the best I can.
I know that in order to subtract the two fractions you need to...
1/3 - 5/6
2/6 - 5/6 = 3/6 = 1/2
Ok so now we have
3/6 divided by 5/6
for dividing these things it is copy dot flip
3/6*6/5 = 3/5
This would then be 3/5
I am not positive if this is correct but going off of what I have learned I think it should be ok.
