помогите мне пожалуйста...

1) |-3 + 2*|-5| | + |-11-3| = |-3 + 2*5| + |-14| = |7| + 14 = 7 + 14 = 21
2) 5/6 : (2 2/3) = x : 2,4
5/6 : 8/3 = x : 24/10
5/6*3/8 = x*5/12
5/16 = x*5/12
x = 5/16*12/5 = 12/16 = 3/4

spasibo3pajbrh |-3+2•|-5||+|-11-3|=|-3+2•5|+|-14|=|7|+14=7+14=21

$\frac{5}{6} \div 2 \frac{2}{3} = x \div 2.4$
$x = \frac{5}{6} \div \frac{8}{3} \times 2.4$
$x = \frac{5}{6} \times \frac{3}{8} \times 2.4$
$x = \frac{5 \times 2.4}{16}$
$x = \frac{12}{16}$
$x = \frac{3}{4}$
