Ответ:

  1. \(|(-4.8):(-0.6)|-|(-2.5)·(-3.2)|=|8|-|8|=8-8=0\).
  2. \(\left(|-\frac{5}{4}|+|\frac{3}{2}|\right)·\left(|-\frac{2}{5}|+|\frac{1}{5}|\right)=\left(\frac{5}{4}+\frac{3}{2}\right)·\left(\frac{2}{5}+\frac{1}{5}\right)=\frac{11}{4}·\frac{3}{5}=\frac{33}{20}\).
  3. \(\frac{|-3.6|+|-2.4|}{|-\frac{3}{4}|+|\frac{1}{4}|}=\frac{3.6+2.4}{\frac{3}{4}+\frac{1}{4}}=\frac{6}{1}=6\).
  4. \(\left(|-\frac{7}{3}|-|-\frac{2}{3}|\right)·(|1.5|+|-0.5|)=\left(\frac{7}{3}-\frac{2}{3}\right)·(1.5+0.5)=\frac{5}{3}·2=\frac{10}{3}\).

Ответ: 1) 0; 2) \(\frac{33}{20}\); 3) 6; 4) \(\frac{10}{3}\).
