Szczegółowe wyjaśnienie:
a) 0,2 * 5/6 * 3 = 1/5 * 5/6 * 3 = 1*5*3/5*6 = 15/30 = 1/2
d) 5/6 : 1,5 : 10/9 = 5/6 : 3/2 : 10/9 = 5/6 * 2/3 * 9/10 =
= 5*2*9/6*3*10 = 9/6*3 = 9/18 = 1/2
e) 1 13/15 : 1 1/5 : 14 = 28/15 : 6/5 : 14 = 28/15 * 5/6 * 1/14 =
= 28*5*1/15*6*14 = 10/15*6 = 10/80 = 1/8
f) 5/7 : 1,75 : 1 1/14 = 5/7 : 175/100 : 15/14 =
= 5/7 * 100/175 * 14/15 = 5*100*14/7*175*15 = 100*14/7*175*3 =
= 200/175*3 = 40/35*3 = 8/7*3 = 8/21
