Question

6класс,лёгкое уравнение. 1 целая 1/5 * (2/3х+1/6)=2.6

Answer 1

$1 \frac{1}{5}*( \frac{2}{3}x+ \frac{1}{6})=2.6$
$( \frac{2}{3}x+ \frac{1}{6} )= 2 \frac{3}{5}:1 \frac{1}{5}$
$\frac{2}{3}x+ \frac{1}{6}= \frac{13}{5}: \frac{6}{5}$
$\frac{2}{3}x+ \frac{1}{6}= \frac{13}{5}* \frac{5}{6}$
$\frac{2}{3}x+ \frac{1}{6}= \frac{13}{6}$
$\frac{2}{3}x=\frac{13}{6}- \frac{1}{6}$
$\frac{2}{3}x= \frac{12}{6}$
$\frac{2}{3}x=2$
$x=2:\frac{2}{3}$
$x=2*\frac{3}{2}$
$x=3$
