Odpowiedź:
2/9 * 6 = 12/9 = 1 i 3/9 = 1 i 1/3
5/9 * 3/10 = 1/6
2 i 2/5 * 10 = 12/5 * 10 = 120/5 = 24
3/8 : 4/7 = 3/8 * 7/4 = 21/32
3 i 1/3 : 5/4 = 10/3 * 4/5 = 8/3 = 2 i 2/3
2 i 2/3 : 3 i 5/9 = 8/3 * 9/32 = 3/4
A. 2/9 x 6/1 = 12/9 = 1 3/9 = 1 1/3
B. 15/90 = 6
C. 12/5 x 10/1 = 12/5 = 2 2/5
D. 3/8 x 7/4 = 21/32
E. 10/3 x 4/5 = 40/15 = 2 10/15 = 2 2/3
F. 8/3 : 32/9 = 8/3 x 9/32 = 72/96
