Odpowiedź:
a)
5/6 * 3/5 = 1/2
2/9 * 6/7 = 2/3 * 2/7 = 4/21
1 4/9 * 12 = 13/9 * 12 = 13/3 * 4 = 52/3 = 17 1/3
2/7 * 3 1/2 = 2/7 * 7/2 = 1
b)
(3/4)² = 9/16
(3/7)² = 9/49
(2/3)³ = 8/27
(2/5)² = 4/25
c)
(1 1/4)² = (5/4)² = 25/16 = 1 9/16
(1 1/4)³ = (5/4)³ = 125/64 = 1 61/64
(1 2/3)³ = (5/3)³ = 125/27 = 4 17/27
(2 1/2)² = (5/2)² = 25/4 = 6 1/4
