Szczegółowe wyjaśnienie:
b)
- 3 3/8 : 5 1/16 = (- 24/8 - 3/8) : (80/16 + 1/16) =
(- 27/8) : (81/16) =
- 27/8 *16/81 = - 27 *16/8 *81 = - 16/8 *3 = - 16/24 = - 2/3
c)
-1 1/7 : 1 11/24 : 3/5 = - 8/7 : 35/24 : 3/5 =
= - 8/7 *24/35 *5/3 = - 8 *24 *5/7 *35 *3 =
= - 8 *8 /7 *7 = - 64/49 = - 49/49 - 15/49 = - 1 15/49
d)
3 1/2 - 3 1/6 : (- 2 1/9) = 7/2 - 19/6 : (-19/9) =
= 7/2 - 19/6 *(-9/19) =
= 7/2 - (-9/6) = 21/6 + 9/6 = 30/6 = 5
