Odpowiedź:
a)
2/3 = 8/12 < 3/4 = 9/12
b)
3/5 = 21/35 > 4/7 = 20/35
c)
4/7 = 36/63 < 7/9 = 49/63
d)
2/9 = 20/90 < 7/10 = 63/90
e)
5/6 = 55/66 > 9/11 = 54/66
f)
3/5 = 12/20 < 3/4 = 15/20
g)
5/7 = 15/21 > 2/3 = 14/21
Szczegółowe wyjaśnienie:
a)
2/3 = 8/12
3/4 = 9/12
8/12 < 9/12 ⇒ 2/3 < 8/12
b)
3/5 = 21/35
4/7 = 20/35
21/35 > 20/35 ⇒ 3/5 > 4/7
c)
4/7 = 36/63
7/9 = 49/63
36/63 < 49/63 ⇒ 4/7 < 7/9
d)
2/9 = 20/90
7/10 = 63/90
20/90 < 63/90 ⇒ 2/9 < 7/10
e)
5/6 = 55/66
9/11 = 54/66
55/66 > 54/66 ⇒ 5/6 > 9/11
f)
3/5 = 12/20
3/4 = 15/20
12/20 < 15/20 ⇒ 3/5 < 3/4
g)
5/7 = 15/21
2/3 = 14/21
15/21 > 14/21 ⇒ 5/7 > 2/3
h)
1/2 = 7/14
3/7 = 6/14
7/14 > 6/14 ⇒ 1/2 > 3/7
