Answer 2

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

               Given data:- $\frac{7}{8} +\frac{-13}{-7} .$

               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,

           $\begin{array}{l}\frac{7}{8}+\frac{-13}{-7} \\\\=\frac{7}{8}+\frac{13}{7} \\\\=\frac{7 \times 7}{8 \times 7}+\frac{13 \times 8}{7 \times 8} \\\\=\frac{49}{56}+\frac{104}{56} \\\\=\frac{49+104}{56} \\\\=\frac{153}{56}\end{array}$

       Hence we will get the value is $\frac{153}{56} .$
