Odpowiedź:

(3/4 - 1/2) * 3 i 1/5 = (3/4 - 2/4) * 3 i 1/5 = 1/4 * 16/5 = 4/5

7/8 * 4/5 - 2/3 * 6/14 = 7/10 - 2/7 = 2/10 = 1/5

2 i 1/3 * (1 i 3/4 - 7/8) = 2 i 1/3 * (1 i 6/8 - 7/8) = 2 i 1/3 * (14/8 - 7/8 ) = 7/3 * 7/8 = 49/24 = 2 i 1/24

3 i 1/5 * 1/2 - 5/7 * 1 i 2/5 = 16/5 * 1/2 - 5/7 * 7/5 = 8/5 - 1 = 1 i 3/5 - 1 = 3/5

1/5 * (3 i 3/7 - 2/7 * 5 i 1/2) = 1/5 * (3 i 3/7 - 2/7 * 11/2) = 1/5 * (3 i 3/7 - 11/7) = 1/5 * (3 i 3/7 - 1 i 4/7) = 1/5 * (2 i 10/7 - 1 i 4/7) = 1/5 * 1 i 6/7 = 1/5 * 13/7 = 13/35
