1) -0,2

2) 39,5

3) -25,5

4) -12,9 + 8,9 = -4

$5) \frac{7}{8} - 1 = \frac{7 - 8}{8} = \frac{ - 1}{8} = - \frac{1}{8}$

$6) - \frac{2}{9} - 3 = - \frac{ 2+27 }{9} = - \frac{29}{9} = - 3 \frac{2}{9}$

$7) - \frac{13}{3} + 5 \frac{1}{3} = - \frac{13}{3} + \frac{16}{3} = \frac{ - 13 + 16}{3} = \frac{3}{3} = 1$

$8)2 \frac{5}{9} + 1 \frac{4}{9} = (2 + 1) + ( \frac{5}{9} + \frac{4}{9} ) = 3 + \frac{5 + 4}{9} = 3 + \frac{9}{9} = 3 + 1 = 4$
