Here is your original question:
1%2F6+%2B+5%2F8
--
When you add or subtract fractions, follow these steps:
(1) get a common denominator
we don't have one so we have to find it. Least common multiple of 6 and 8 is 24.
--
(2) change your numerators.
1/6 - -> 4/24
5/8 - -> 15/25
Now we have
4%2F24+%2B+15%2F24
--
(3) add, or subtract, the numerator. In this case we add only the tops to get
19/24
--
(4) reduce if needed.
we cant, so our final answer is:
19%2F24
