Dont need it anymore
\(6(\frac{4}{3}(14\div\frac{1}{7}))\div\frac{13}{10}= 6(\frac{4}{3}(14\cdot7))\cdot\frac{10}{13}= 6(\frac{4}{3}(98))\cdot\frac{10}{13}= 6(\frac{392}{3}))\cdot\frac{10}{13}=784\cdot\frac{10}{13}=\frac{7840}{13}\)or \(603 \frac{1}{13}\)
Please do not delete you question, even if you do not need help anymore :)
