Odpowiedź:

2 i 1/2 * 5 i 1/3 = 5/2 * 16/3 = 40

3 i 3/4 * 4 i 1/5 = 15/4 * 21/5 = 63/4 = 15 i 3/4

5 i 6/7 * 4 i 2/3 = 41/7 * 14/3 = 82/3 = 27 i 1/3

4/5 * 2/9 * 6/7 * 7/8 = 8/45 * 6/7 * 7/8 = 48/360 = 24/180 = 4/30 = 2/15

4/7 * 1 i 3/4 * 3 i 1/2 = 4/7 * 7/4 * 7/2 = 1 * 7/2 = 7/2 = 3 i 1/2

1 i 5/8 * 3 i 1/5 * 2/26 = 13/8 * 16/5 * 2/26 = 26/5 * 2/26 = 2/5
