Сначала находим модуль каждого числа, затем выполняем арифметические действия.

а) |-8| - |-5| = 8 - 5 = 3
б) |-10| - |-15| = 10 - 15 = -5
в) |240| : |-80| = 240 : 80 = 3
г) |-710| + |-290| = 710 + 290 = 1000
д) |-2,3| + |3,7| = 2,3 + 3,7 = 6
е) |-4,7| - |-1,9| = 4,7 - 1,9 = 2,8
ж) |28,52| : |-2,3| = 28,52 : 2,3 = 12,4
з) |0,1| \(\cdot\) |-10| = 0,1 \(\cdot\) 10 = 1
и) |\(\frac{4}{5}\)| - |-\(\frac{2}{3}\)| = \(\frac{4}{5}\) - \(\frac{2}{3}\) = \(\frac{12}{15}\) - \(\frac{10}{15}\) = \(\frac{2}{15}\)
к) |-2\(\frac{3}{11}\)| \(\cdot\) |-\(\frac{9}{14}\)| = 2\(\frac{3}{11}\) \(\cdot\) \(\frac{9}{14}\) = \(\frac{25}{11}\) \(\cdot\) \(\frac{9}{14}\) = \(\frac{225}{154}\) = 1\(\frac{71}{154}\)
л) |3\(\frac{1}{7}\)| : |-\(\frac{1}{9}\)| = 3\(\frac{1}{7}\) : \(\frac{1}{9}\) = \(\frac{22}{7}\) : \(\frac{1}{9}\) = \(\frac{22}{7}\) \(\cdot\) 9 = \(\frac{198}{7}\) = 28\(\frac{2}{7}\)
м) |-8\(\frac{1}{3}\)| : |\(\frac{5}{9}\)| = 8\(\frac{1}{3}\) : \(\frac{5}{9}\) = \(\frac{25}{3}\) : \(\frac{5}{9}\) = \(\frac{25}{3}\) \(\cdot\) \(\frac{9}{5}\) = \(\frac{225}{15}\) = 15
