Пошаговое объяснение:

$\[\begin{gathered}\left|{-7}\right|+\left|{-14}\right|=7+14=21\hfill\\\left|{\frac{3}{4}}\right|+\left|{-\frac{3}{4}}\right|=\frac{3}{4}+\frac{3}{4}=\frac{6}{4}=1,5\hfill\\\left|{-20}\right|+\left|{-\frac{5}{6}}\right|=20+\frac{5}{6}=20\frac{5}{6}\hfill\\\left|{1,7}\right|-\left|{-\frac{1}{5}}\right|=1,7-\frac{1}{5}=1,7-0,2=1,5\hfill\\\end{gathered}\]$

$\[\begin{gathered}\left|{-6\frac{1}{2}}\right|+\left|{2\frac{3}{4}}\right|=6\frac{1}{2}+2\frac{3}{4}=8\frac{5}{4}=9\frac{1}{4}\hfill\\24,4-\left|{-12}\right|-\left|{-3}\right|=24,4-12-3=9,4\hfill\\2\frac{3}{4}+\left|{11-7}\right|=2\frac{3}{4}+4=6\frac{3}{4}\hfill\\\left|{34}\right|-\left|{-10}\right|=34-10=24\hfill\\\end{gathered}\]$
