Вычислите: |-1,9|= -1-1- |-35|+|-41| = 14-1-2= |-5--:4= -1-3= |-18|+|-43| = |-3|-|-2,5 = |-3|1= -17||-3|- |-20|= -3+-:3= |-3,5-4 = |-18||-2|+|-22|= -3-2=

\(|-1,9| = 1,9\)

\(|-\frac{5}{9}| = \frac{5}{9}\)

\(|-35| + |-41| = 35 + 41 = 76\)

\(4\frac{1}{5} - |-2\frac{1}{3}| = \frac{21}{5} - \frac{7}{3} = \frac{21 \cdot 3 - 7 \cdot 5}{15} = \frac{63 - 35}{15} = \frac{28}{15} = 1\frac{13}{15}\)

\(|-5\frac{5}{8}| - |-\frac{1}{2}| : 4 = \frac{45}{8} - \frac{1}{2} : 4 = \frac{45}{8} - \frac{1}{2} \cdot \frac{1}{4} = \frac{45}{8} - \frac{1}{8} = \frac{44}{8} = \frac{11}{2} = 5\frac{1}{2}\)

\(|\frac{7}{3}| - |-3\frac{1}{6}| = \frac{7}{3} - \frac{19}{6} = \frac{7 \cdot 2 - 19}{6} = \frac{14 - 19}{6} = -\frac{5}{6}\)

\(|-18| + |-43| = 18 + 43 = 61\)

\(|-3| \cdot |-2,5| = 3 \cdot 2,5 = 7,5\)

\(|-3\frac{3}{7}| : |1\frac{1}{7}| = \frac{24}{7} : \frac{8}{7} = \frac{24}{7} \cdot \frac{7}{8} = 3\)

\(|-17| \cdot |-3| - |-20| = 17 \cdot 3 - 20 = 51 - 20 = 31\)

\(|-\frac{3}{6}| + |-\frac{1}{2}| : 3 = \frac{1}{2} + \frac{1}{2} : 3 = \frac{1}{2} + \frac{1}{2} \cdot \frac{1}{3} = \frac{1}{2} + \frac{1}{6} = \frac{3 + 1}{6} = \frac{4}{6} = \frac{2}{3}\)

\(|-3,5| \cdot |-4| = 3,5 \cdot 4 = 14\)

\(|-1\frac{1}{3}| : |-1\frac{1}{9}| = \frac{4}{3} : \frac{10}{9} = \frac{4}{3} \cdot \frac{9}{10} = \frac{2 \cdot 3}{5} = \frac{6}{5} = 1\frac{1}{5}\)

\(|-18| \cdot |-2| + |-22| = 18 \cdot 2 + 22 = 36 + 22 = 58\)

\(|-\frac{3}{8}| - |-\frac{1}{4}| : 2 = \frac{3}{8} - \frac{1}{4} : 2 = \frac{3}{8} - \frac{1}{4} \cdot \frac{1}{2} = \frac{3}{8} - \frac{1}{8} = \frac{2}{8} = \frac{1}{4}\)
