Question

-8/19+(-2/57) - chapter rational numbers.​

Answer 1

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

              Given data:- $\frac{-8}{19} +\frac{-2}{57}.$

              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,

                   $\begin{array}{l}\frac{-8}{19}+\frac{-2}{57} \\\\=\frac{-8 \times 3}{19 \times 3}+\frac{-2}{57} \\\\=\frac{-24}{57}+\frac{-2}{57} \\\\=\frac{-24+-2}{57} \\\\=-\frac{26}{57}\end{array}$

       Hence we will get the value is $\frac{-8}{19} +\frac{-2}{57}=\frac{-26}{57}.$
