Convert to a common denominator and then add the numerators.
27, 43 and 10 have no common integer factors. In fact, 43 is a prime number. Therefore, in this case the lowest common denominator is the product of 27x43x10, which is 11,610.

okay after i have the common denominator which is 11,610. whats the next step?

Rewrite every fraction with that denominator and add the numerators.
(3010 + 270 + 3483)/11,610
= 6763/11,610
See of that can be reduced to lower terms. I don't think it can.
