Answer 1

$\frac{1}{6} x-0,82= \frac{3}{8} x-1,37 \\ \frac{3}{8} x- \frac{1}{6} x=1,37-0,82 \\ \frac{5}{24} x=0,55 \\ x= \frac{55}{100} * \frac{24}{5} \\ x= \frac{66}{25} =2 \frac{16}{25}=2,64$
==================
$7,6:x=2 \frac{1}{9} :2 \frac{4}{9} \\ 2 \frac{1}{9}x=7,6*2 \frac{4}{9} \\ \frac{19}{9}x= \frac{76}{10}* \frac{22}{9} \\ \frac{19}{9} x= \frac{836}{45} \\ x= \frac{836}{45} * \frac{9}{19} \\ x= \frac{44}{5} =8 \frac{4}{5} =8,8$
