Question

Нижнее решите пожалуйста !!!!

Answer 1

$t:2 \frac{3}{23}=3 \frac{2}{7}: \frac{1}{4}$
$t=3 \frac{2}{7}: \frac{1}{4} *2 \frac{3}{23}$
$t= \frac{23}{7}* \frac{4}{1} * \frac{49}{23}$
$t= 28$

$\frac{3+z}{8} = \frac{6}{11}$
$3+z = \frac{6}{11} *8$
$3+z = \frac{48}{11}$
$3+z =4 \frac{4}{11}$
$z =4 \frac{4}{11} -3$
$z =1 \frac{4}{11}$
