rearrange the and find the sum
-3+7/10+8/7+(-2) +5/14+ -4/5​

Answer 1

${\implies} (- 3) + \frac{7}{10} + \frac{8}{7} + ( - 2) + \frac{5}{14} + ( \frac{ - 4}{5} )\\ \\{\implies} - 3 + \frac{7}{10} + \frac{8}{7} - 2+ \frac{5}{14} - \frac{ 4}{5} \\ \\ {\implies} \frac{ - 210 + 49 + 80 - 140 + 25 - 56}{70} \\ \\{\implies} \frac{ - 252}{70} = 196.8$
