Odpowiedź:
a 5/3 : 13/6 = 5/3 * 6/13 = 15/13
b 8/5:36/5 = 8/5 * 5/36 =8 /36 = 4 / 18 = 2/9
c 18/7 : 9 /4 = 18 /7 * 4/9 = 8 / 7
d 13 /1 0 : 13/12 = 13/10 * 12/13 = 12/10 = 6/5
e 20/3 : 5/2 = 20/3 * 2/5 = 4/3 * 2 = 8 /3
f 12/5 : 8/5 = 12/5 * 5/8 = 12/8 = 6/4 = 3/2
g 15/8 : 15/4 = 15/8 * 4/15 = 4/8 = 2/4 = 1/2
h 22/5 : 11 /4 = 22/5 * 4/11 = 4/5
