If you are asking one-eighth plus two-thirds then the answer is 14/16 which reduces to 7/8. Find the least common denominator (16) If you are asking one over one-eith plus two-thirds then the answer is 8 and two-thirds. This is because one over one-eighth means one divided by one eighth. You would invert the denominator (one-eighth) and multiply it to one. Eight over one is the same as eight. One times eight equals eight. Then add eight to two-thirds. This equals eight and two thirds (8 2/3).
