Answer 1

Ответ:

1) 21-(5-8)=21-(-3)=24

2) 3,7-(4-5,3)=5

$3) \: \frac{1}{6} - (\frac{5}{12} - \frac{7}{12}) = \frac{1}{6} - ( - \frac{2}{12}) = \frac{2}{12} - ( - \frac{2}{12} ) = \frac{4}{12} = \frac{1}{3}$

4) -13-(20-32)= -13-(-8)= -5

5) -4,5-(7-9,5)=-4,5-(-2,5)=-2

$6) \: - \frac{5}{8} - ( \frac{5}{8} - 1) = - \frac{5}{8} - ( - \frac{3}{8} ) = - \frac{2}{8}$

7) -18-(9-5)=-18-(4)= -22

8) -0,25-(3-2,25)= -1

$9) \: - \frac{2}{9} - (1 - \frac{8}{9} ) = - \frac{2}{9} - ( \frac{1}{9} ) = - \frac{3}{9} = - \frac{1}{3}$
