Answer 2

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

           Given data:- $\frac{-6}{3} +\frac{-5}{7} .$

           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,

          $\begin{array}{l}\frac{-6}{3}+\frac{-5}{7} \\\\=\frac{-6 \times 7}{3 \times 7}+\frac{-5 \times 3}{7 \times 3} \\\\=\frac{-42}{21}+\frac{-15}{21} \\\\=\frac{-42+-15}{21} \\\\=\frac{-57}{21} \\\\=\frac{-57 \div 3}{21 \div 3} \\\\=-\frac{19}{7}\end{array}$

         Hence we will get the value is $-\frac{19}{7} .$
