PILNE NA JUTRO!! Wykonaj dodawanie!!! a) 1/4+ 3/4=... b) 3/5+4/5=... c) 5/7+1 i 4/7=... d) 2 i 5/6+ 3 i 1/6 =... e) 5/12 + 7/12 + 9/12=... f) 2 i 3/8+ 3 i 5/8+ 4 i 7/8=...  

a) 1/4+ 3/4=...4/4 = 1 b) 3/5+4/5=...7/5 = 1 2/5 c) 5/7+1 i 4/7=... 9/7 =1 2/7   tyle umiem :]

a) 1/4 + 3/4 = 4/4 = 1 b) 3/5 + 4/5 = 7/5 = 2 i 2/5 c) 5/7 + 1 i 1 4/7 = 5/7 + 11/7 = 16/7 = 2 i 2/7 d) 2 i 5/6 + 3 i 1/6 = 17/6 + 19/6 = 36/6 = 6 e)5/12 + 7/12 + 9/12 = 21/12 = 1 i 9/12 f) 2 i 3/8 + 3 i 5/8 + 4 i 7/8 = 19/8 + 29/8 + 39/8 = 87/8 = 10 i 7/8

a)=1 b)=9/5=1i 4/5 c)5/7+11/7=16/7=2i 2/7 d)17/6+19/6=36/6=6 e)5/12+7/12+9/12=1/12=1 i 9/12=1 i 3/4 f)19/8+29/8+39/8=87/8=10 i 7/8
