Question

\(\frac{1}{7}.\left(\frac{-23}{10}\right)+\left(\frac{77}{10}\right)\)

Answer 1

\(\frac{1}{7}.\left(\frac{-23}{10}\right)+\frac{77}{10}\)

\(=\frac{-23}{70}+\frac{77}{10}\)

\(=\frac{258}{35}\)

Answer 2

\(\frac{1}{7}.\left(\frac{-23}{10}\right)+\frac{77}{10}\)

= \(\frac{-23}{70}+\frac{77}{10}\)

= \(\frac{258}{35}\)

Answer 3

\(\frac{1}{7}\cdot\left(\frac{-23}{10}\right)+\left(\frac{77}{10}\right)\)

\(=-\frac{23}{70}+\frac{77}{10}=\frac{-23}{70}+\frac{539}{70}=\frac{516}{70}=\frac{258}{35}\)

Answer 4

\(\frac{17}{10}.\left(\frac{-23}{10}\right)+\left(\frac{77}{10}\right)\)

Answer 5

\(\frac{1}{7}.\left(\frac{-23}{10}\right)+\left(\frac{77}{10}\right)\)

\(=-\frac{23}{70}+\frac{77}{10}=\frac{-23}{70}+\frac{539}{70}=\frac{516}{70}=\frac{258}{35}\)

Answer 6
