Odpowiedź:
a=2+1/3
b=2-1/2+1/3
oblicz
a + b = 2 + 1/3 + 2 - 1/2 + 1/3 = 3 1/2 + 2/3 = 3 3/6 + 4/6 = 3 7/6 = 4 1/6
a-b= 2 + 1/3 - 2 + 1/2 - 1/3 = 1/2
a×b= (2 + 1/3)(2 - 1/2 + 1/3) = 2 1/3 * (1 3/6 + 2/6) = 7/3 * 1 5/6 = 7/3 * 11/6 = 77/18 = 4 5/18
a:b= (2+1/3) : (2-1/2+1/3) = 2 1/3 : (1 3/6 + 2/6) = 7/3 : 1 5/6 = 7/3 : 11/6 = 7/3 * 6/11 = 14/11 = 1 3/11
