Odpowiedź:
zad 12
a) = 10/3
b) = 1/2
c) = 18/5 · 10 = 36
d) = 9/4 · 2/3 = 3/2 = 1 1/2
e) = 9/2 = 4 1/2
f) = 16
Szczegółowe wyjaśnienie:
B) 4/9*3/8=12/72=6
C) 3 3/5 * 10= 18/5 * 10/1 = 90/1 = 90
D) 2 1/4 * 2/3 = 9/4 * 2/3 = 3/2 = 1 1/2
E) 1 7/8 * 2 2/5 = 15/8 * 12/5 = 9/2 = 4 1/2
F)3 1/3 * 4 4/5 = 10/3 * 24/5 = 16/1 = 16
