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.

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.
