b) 8-(2- ) + 3 =
trzy jedna czwarta- trzy czwarte= ..... - 2 trzecie = ......
dwa trzy ósme =
dwa trzy ósme - siedem ósmych = ..... - siedem ósmych =

Answer 1

4 - (5 - 2 i 3/5 ) = 4 - (4 i 5/5 - 2 i 3/5 = 3 i 5/5 - 2 i 2/5 = 1 i 3/5
8 - ( 2 - 3/7 ) + 3 i 3/7 = 8 - ( 1 i 7/7 - 3/7 ) + 3 i 3/7 = 7 i 7/7 - 4 i 7/7 = 3
3 i 1/4 - 3/4 = 2 i 5/4 - 3/4 = 2 i 2/4 - 2/3 = 2 i 6/12 - 8/12 = 1 i 18/12 - 8/12 = 1 i 10/12 = 1 i 5/6
2 i 3/8 - 7/8 = 1 i 11/8 - 7/8 = 1 i 4/8 - 7/8 = 12/8 - 7/8 = 5/8
