Ułamki, zrobicie mi te przykłady? a) 2 i 1/4 + 3 i 2/3 - 1 i 3/5 = b) 1/18 - 5/6 + 7/24 = c) (5 i 4/5 - 3i 5/6) - (3i 5/12 - 2 i 3/4)= d) (3 i 7/10 - 2/3) - (5 i 2/3 + 7i 1/15 - 4 i 3/5)= e) (15/23 - 3/46)-(-7/2)+7/23=

b) 1/18 - 5/6 + 7/24 = 1/18 - 15/18 + 7/24 = -14/18 + 7/24 ...
c) ( 5 i 4/5 - 3 i 5/6 ) - (3 i 5/12 - 2 i 3/4) = 29/5 - 23/6 = 174/30 - 115/30 = 168/30
