Ответ:

$1)16 - 29 + 14 - 48 = - 47 \\ 2) - 3.2 - 7.8 - 5.4 + 4.6 = - 11.8 \\ 3) - 4.28 - 1.53 + 7.85 - 9.06 = - 7.02 \\ 4) - 5 \frac{3}{8} + 4 \frac{5}{6 } + 2 \frac{1}{4 } = - \frac{129 + 695}{24} + \frac{9}{4} = \frac{566 + 54}{24} = \frac{620}{24} = 25 \frac{20}{24} = 25 \frac{5}{6} \\ \frac{ - 54 - 35 + 68}{15} + \frac{110 + 67 + 30}{60} = - \frac{44 + 207}{60} = \frac{163}{60} 2 \frac{43}{6}$
