The answer is 8 4/8 or when reduced is 8 1/2.
3/8
three eights
2
Converting this to eights, it becomes: 2 eights + 4 eights + 1 eight = 7 eights.
_76
if 4 and eight eights is subtracted by 3 and three eights, then you get 1 and five eights
* -5/8
3 and 7 eights
2 1/2
It is: 1/8 minus 1/4 = -1/8
5/8 minus 1/2 is 1/8.
Expressed as a proper fraction in its simplest form, 3/4 - 5/8 = 1/8 or one eighth.
