|-3 1/2| - |-1/2 + 5/2|=
|1 - 2 * 0.7| - |0.7|=

Answer 1

Ответ:

$| - 3 \frac{1}{2} | - | - \frac{1}{2} + \frac{5}{2 } | = 3\frac{1}{2} - |2| = \frac{7}{2} - 2 = \frac{7 - 4}{2} = \frac{3}{2} = 1 \frac{1}{2} = 1.5 \\ \\ |1 - 2 \times 0.7| - |0.7| = |1 - 1.4| - 0.7 = | - 0.4| - 0.7 = 0.4 - 0.7 = - 0.3$
