Question

the value of -6/7- [-2/14]

Answer 1

Answer:

Step-by-step explanation:

( - 6/7) - ( - 2/14)

= ( - 6/7 ) - ( - 1/7)

= ( - 6/7 ) + ( 1/7 ) ( ∵ - × - = + )

= ( - 6 + 1 ) / 7

= -5/7 is the answer.

Answer 2

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

           Given data:-  $\frac{-6}{7} -\frac{-2}{14} .$

           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,

          $\begin{array}{l}\frac{-6}{7}-\frac{-2}{14} \\\\=\frac{-6 \times 2}{7 \times 2}-\frac{-2}{14} \\\\=\frac{-12}{14}-\frac{-2}{14} \\\\=\frac{-12--2}{14} \\\\=\frac{-10}{14} \\\\=\frac{-10 \div 2}{14 \div 2} \\\\=-\frac{5}{7}\\\\=-0.7142.\end{array}$

      Hence we will get the value $-\frac{5}{7}$ or $-0.7142.$
