Question

Solve $5\frac{2}{7}-\frac{8}{9}+\left(\frac{-3}{14}\right)-21\frac{3}{19}.$

Answer 1

$5\frac{2}{7}-\frac{8}{9}+\left(\frac{-3}{14}\right)-21\frac{3}{19}$

$=\frac{37}{7}-\frac{8}{9}-\frac{3}{14}-\frac{402}{19}$

$=\frac{12654-2128-513-50652}{2394}$

$=\frac{-40639}{2394}$

$=-16\frac{2335}{2394}$
