Answer 1

Answer:

-19/54

Step-by-step explanation:

11/-18 = (11*-1)/(-18*-1) = -11/18

(-11/18)+(7/27)

L.C.M of 18 and 27 is 54

-11/18= -33/54

7/27= 14/54

-33/54 + 14/54

-33+14/54

-19/54

Answer 2

• We have to evaluate the above expression by using the given data.

             Given data:- $\frac{11}{-18} +\frac{7}{27} .$

             To find:- Value of the given expression.

             Solution:-

• We will take the LCM of the denominators, and make denominators the same.

• We will Convert the given fractions to equivalent fractions with the denominator as the LCM.

• Adding the numerators over the denominators.

        Therefore,

            $\begin{array}{l}\frac{11}{-18}+\frac{7}{27} \\\\=\frac{-11}{18}+\frac{7}{27} \\\\=\frac{-11 \times 3}{18 \times 3}+\frac{7 \times 2}{27 \times 2} \\\\=\frac{-33}{54}+\frac{14}{54} \\\\=\frac{-33+14}{54} \\\\=-\frac{19}{54}\\\end{array}$

   Hence we will get the value is $-\frac{19}{54} .$
