b) 3,2 : (0,8 - 2/5) = 3,2: 2/5 = 3,2 : 0,8 = 4
c) 4,8 + 1 1/3 * (1,1 - 0,6) = 4,8 + 1 1/3 * 0,5 = 4,8 - 2/3 = 4 2/15
d) (1,5 - 1 1/3) * 2 2/5 - 0,1 = 1 1/6 * 2 2/5 - 0,1 = 2,7
e) 2/3 + 1/2 - 0,5 7/6 - 0,5 = 2/3
--------------------- = ----------------------- = 2/3 : 0,1 = 2/3 * 10/1 =
0,2 - 0,8 * 1/8 0,2 - 0,1 = 0,1
= 20/3 = 6 2/3
f) 4 ,4 - 2/3 * 1,8
------------------------------------------------------------------- =
3/8 * 4 ² * 1/4 * 2 ³
4,4 - 6/5 = 3,2
------------------------- = 3,2 : 12 = 0,3
3/8 * 16 * 1/4 * 8 = 12
g) 4,8 + 1/3 * (1,1 - 0,6) = 4,8 + 1/3 * 0,5 = 4,8 + 1/6 = 4 11/30
(nie jestem pewna czy dobrze rozwiazalam F )
