The question is we have to simplify the expression

The expression is

 -  \frac{9}{27}  +  \frac{18}{39}

we can solve the above expression by taking the LCM

The LCM for the above expression is

(27) \times (39) = 1053

multiply both numerator and denominator with the corresponding number to get the LCM

 (-  \frac{9}{27}  \times 39) + ( \frac{18}{39}  \times 27) \\  \frac{ - 351}{1053}  +  \frac{486}{1053}  \\

Now the denominator of the two terms is equal.

so just subtract the numbers as it is and put the sign of the largest number.

 \frac{ - 351 + 486}{1053} \\  =  \frac{135}{1053}  \\  = 0.12

Therefore, the final answer for the given expression is 0.12.
