Answer 1

Ответ:

$1) = 3.46 - 5.46 = - 2 \\ 2) = 5.34 - 2.72 + 4.34 + 6.72 = - 8.06 + 11.06 = 3 \\ 1) = 37 - 50 + 22 + 13 - 28 = - 6 \\ 2) = - 1.32 + 2.41 + 3.77 - 4.68 + 0.59 = 0.77 \\ 3) = - \frac{16}{25} + \frac{4}{27} + \frac{21}{25} - \frac{13}{27} = \frac{16 + 21}{25} + \frac{4 - 13}{27} = \frac{5}{25} + \frac{ - 9}{27} = \frac{1}{5} + \frac{ - 1}{3} = \frac{3 - 5}{15} = \frac{ - 2}{15} \\ \\ = - 1.9 + m + 3.24 - 7.1 + n - 5.24 = - 11 + m + n = - 11 + ( - 14.8) + 2.6 = - 23.2$
