Odpowiedź:
a)
4/9 * 3/4 = 1/3
b)
5/8 : 7/12 = 5/8 * 12/7 = 5/2 * 3/7 = 15/14 = 1 1/14
c)
7/8 * 24/33 = 7 * 3/33 = 7 * 11 = 77
d)
1 1/8 * 4/15 = 9/8 * 4/15 = 3/2 * 1/5 = 3/10
e)
2 2/5 : 5 = 12/5 * 1/5 = 12/25
f)
1 5/7 : 6 = 12/7 * 1/6 = 2/7
g)
6 1/2 : 3 1/4 = 13/2 : 13/4 = 13/2 * 4/13 = 2
h)
7 1/3 : 2 2/5 = 22/3 : 12/5 = 22/3 * 5/12 = 11/3 * 5/6 = 55/18 = 3 1/18
i)
2 * (13 * 4)/8 = 13 * 4/4 = 13
j)
8 3/4 * 4/7 * 3 = 35/4 * 4/7 = 5
k)
2 1/7 * 7 * 2 2/5 = 15/7 * 7 * 12/5 = 3 * 12 = 36
l)
4 * (15 * 9/12) = 15 * 9/3 = 45
