Explicación paso a paso:

$(3.5)*\left(\frac{10}{14}\right)(1,1)\left(\frac{9}{18}\right)(1,23)\\\\3.5=\frac{35}{10}=\frac{7}{2}\\\\1.1=\frac{11}{10}\\\\1.23=\frac{123}{100}\\\\\frac{10}{14}=\frac{5}{7}\\\\\frac{9}{18}=\frac{1}{2}\\\\(3.5)\left(\frac{10}{14}\right)(1,1)\left(\frac{9}{18}\right)(1,23)=\left(\frac{35}{10}\right)\left(\frac{10}{14}\right)\left(\frac{11}{10}\right)\left(\frac{9}{18}\right)\left(\frac{123}{100}\right)=\\\\=\left(\frac{7}{2}\right)\left(\frac{5}{7}\right)\left(\frac{11}{10}\right)\left(\frac{1}{2}\right)\left(\frac{123}{100}\right)=\frac{7*5*11*1*123}{2*7*10*2*100}=\frac{47355}{28000}=\\\\=\frac{1353}{800}$

$-\left(\frac{-7}{3}\right)\div\left(\frac{-5}{6}\right)=-(-7/3)/(-5/6)=7/3/-5/6=\frac{(7)(6)}{(3)(-5)}=\frac{(7)(6)}{(3)(-5)}=-\frac{42}{15}=-\frac{14}{5}$

$(64/-27)÷(-12/7)=-64/27/-12/7=\frac{(-64)(7)}{(27)(-12)}=\frac{448}{324}=\frac{112}{81}$
