а)
(a-8,4) + (3 2/5 -a) = a - 8,4 + 3 2/5 -a =-8,4 +2,4 =
-6.
б)
(16 5/9 -b) - (8 1/3 -b) = 16 5/9 -b - 8 1/3 +b = 16 5/9 - 8 1/3 = 16 5/9 - 8 3/9 =
8 2/9 .
---------------------------------
4)
- 7 - m +6,71 +n -23/50 = - ( 7 + m - 6,71 - n +23/50) = - (0,29 -n +46/100)=- (0,29 -n +0,46) =
= -(0,75 -n) = n -0,75 . *** -( 3/4 -n) =n - 3/4 ***
