Odpowiedź:
e)
3 3/4 - 2 2/3 + 6 - 3 5/6 = 9 3/4 - 2 4/6 - 3 5/6 = 9 3/4 - 5 9/6 = 9 3/4 - 6 3/6 =
= 9 3/4 - 6 1/2 = 9 3/4 - 6 2/4 = 3 1/4
f)
10 - (2 1/9 - 1/2 + 1 5/6) = 10 - (2 1/9 - 3/6 + 1 5/6) = 10 - (2 1/9 + 1 2/6) =
= 10 - (2 1/9 - 1 1/3) = 10 - (2 1/9 - 1 3/9) = 10 - (1 10/9 - 1 3/9) = 10 - 7/9 = 9 2/9
g)
(4 1/3 - 2 2/5) - (6 3/5 - 5 2/3) = 4 1/3 - 2 2/5 - 6 3/5 + 5 2/3 = 10 - 9 = 1
