Question

Решите.Очень надо!!Заранее спасибо.

Answer 1

$1.\;|-24|+|0|+|47|=24+0+47=71\\2.\;|-50:4|-|8|\cdot|-4,5|=|-12,5|-8\cdot4,5=12,5-36=-23,5\\3.\;\left|5\frac23-7\right|:|2|-\left|-\frac19\right|=\left|-1\frac13\right|:|2|-\frac19=1\frac13:2-\frac19=\frac23-\frac19=\frac59\\\\4.\;\left|5\frac47-3\frac12\right|+|-0,3|=\left|\frac{39}7-\frac72\right|+0,3=\left|\frac{78-49}{14}\right|+\frac3{10}=\\=\frac{29}{14}+\frac3{10}=\frac{145+21}{70}=\frac{166}{70}=2\frac{26}{70}=2\frac{13}{35}$
