Answer 2

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

             Given data:- $\frac{-9}{13} -\frac{-7}{5} .$

             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,

          $\begin{array}{l}\frac{-9}{13}-\frac{-7}{5} \\\\=\frac{-9 \times 5}{13 \times 5}-\frac{-7 \times 13}{5 \times 13} \\\\=\frac{-45}{65}-\frac{-91}{65} \\\\=\frac{-45--91}{65} \\\\=\frac{46}{65}\\\\= 0.70.\end{array}$

      Hence we will get the value $\frac{-9}{13} -\frac{-7}{5} =\frac{46}{65}$ or $0.70.$
