Szczegółowe wyjaśnienie:
4.
a) - 1 3/5 * (-10) = - 8/5 * (-10/1) = - 8/1 * ( -2/1) = 16
b) 3,6 * (-1/4) = 3 6/10 * (-1/4) = 3 3/5 * (-1/4) = 18/5 * (-1/4) = 9/5 * (-1/2) = - 9/10
c) -7 * 1/7 = -1
d) - 3 3/5 * (- 1 2/3) = - 18/5 * (- 5/3) = -6/1 *(-1/1) = 6
5.
a) -6 1/4 :( -5) > 0 , bo < - >*< -> = +
b) -2 : 0,4 < 0 bo <-> * <+> = -
c) 0 : (-2,5) = 0 bo 0 przez cokolwiek się podzieli będzie się równało 0
d) 2/3 : (-2/3) < 0 bo <+> * <-> = -
e) 2 2/3 : 1 1/3 > 0 bo <+> * <+> =+
6. - 1 3/5 : (-4) = -8/5 : (-4/1) = -8/5 * (-1/4) = -2/5 * (-1/1) = 2/5
D.
1 3/5 : (-1/4) =8/5 : (-1/4) = 8/5 * (-4/1) = -32/5 = - 6 2/5
C.
- 1 3/5 : 4 = - 8/5 * 1/4 = -2/5 * 1/1 = - 2/5
A.
-1 3/5 : (-1/4) = -8/5 * (-4/1) = 32/5 = 6 2/5
B.
