Oblicz. 1i3/5+2i4/15= 2i1/4+1i2/3= 1i5/6+7/9= 7/10+4/5+1/2= 3/4+5/7+1i1/2= 7/8+1/2+2/4= 2i1/6+7/10+1i2/5= 1i7/8+1/3+2i5/6= 2i7/12+1i1/15+1/2= DAJE NAJ .    

1 i 9/15 + 2 i 4/15 = 3 i 13/15  2 i 3/12 + 1 i 8/12 = 3 i 11/12  1 i 15/18 + 14/18 = 1 i 29-18 = 2 i 11/18  7/10 + 8/10  + 5/10 = 20/10 = 2  21/28 + 20/28 + 14/28 = 60/28 = 2 i 4/28 = 2 i 1/7  2 i 5/30 + 21/30 + 1 i 12/30 = 3 i 38/30 = 4 i 8/30 = 4 i 4/15  1 i 21/24 + 8/24 + 2 i 20/24 = 3 i 49/24 = 5 i 1/24   2 i 35/60 + 1 i 4/60 + 30/60 = 3 i 69/60 = 4 i 9/60 = 4 i 3/20  -------------------------------------------------------------------------------------------------------- Myślę zo pomogłem ( to są te same liczby tylko ze wspólnym mianownikiem ) .
